Second season with Nova...11's or Bust

[Repointer]

I ended last year with a best of 12.78@103.02. This winter's changes, Transmission rebuilt and new RHS Vortec HP heads. Things to be done as the season progressses, Cal-Tracs, Vortec RPM Air gap, 1.6 Roller rockers, Weld Drag lites, Exhaust tuning, and a few more things I can't think of right now. Goal is 11's on motor, but I will break out the NOS if necesary.;)

Got in two runs last night, the track was crazy crowded. I arrived at 7:30 and didn't get my first run in until after 10:30. No time for any sort of tuning and it looks like I have a traction problem now. Best run.

60 - 2.014
1/8 - 8.26
MPH - 84.80
1/4 - 12.92
MPH 105.09

I think she has 12.5's @ 106+ in her with a little tuning and fixing the traction issue.

The car/driver also weighed 100lbs more yesterday than the end of last year.

[novas4life]

Right on Chris, You picked up 2 mph!! Shows the motor making more ponies.
Definatly some tuning and you'll have some great times.
I drove by PIR last night headed south,and saw the nightmare trying to get in. I could only imagine how crowded it was. I wanted to go watch but I was headed out to go fix an Albertson's.

Freakin rain yesterday cancelled racing today, even though it's sunny out today :rolleyes:

Chris, were your old heads ported at all? Your short times are killin ya!!!

That really sucks!:(

Old heads (041's) were bone stock. I have some work still though to make the most of these heads. I was only running about 34* total advance to start and it liked 38* to 40* last year. No time for any adjustments last night. Also the dominator manifold doesn't match up to the vortec's ports very well, so there should be some more there when I switch intakes. I'm making more torque on the lower end also cause the car pitched sideways off the line, I had to get off it and back on to straighten it out.:)

Every time I had to get out of it for one reason or another, it was the difference between a mid 12 and a low 13.
I think that's where your E.T. went.

I'd guess the MPH might have come from the new trans? Saw you out last Saturday, I only stayed for a bit, man it was definitely packed out there. I think I might go to Woodburn when its time to go racing...better traction and likely more passes.

I wonder? The tranny doesn't seem to have any more of a solid shift from 1-2 and it still flashes to 4100 RPM's?? I didn't notice yet if the hesitation on the 2-3 shift is completely gone. I still need a few more times out before checking into it more.

I'll have to try Woodburn this year. Haven't raced there since the High School drags.:)

[Repointer]

Cal-Tracs Installed. Now I have to learn how to dial them in. 5 runs and all spinning out of the hole. If I can just match my 60' from last year I will hit the 12.4's. The last was the best.

60' - 1.994
1/4 - 12.806
MPH - 106.08

I tried these settings in order, the bottom hole 1 full turn, 1/2 turn, 1 1/2 turns, then switched to the top 1/2 turn and 1/4 turn. I had someone my weight sitting in the car, but it was dark and hard to accurately count the turns.

[novas4life]

106 mph!! You picked up 3 mph-that's great.Get those 60's down and you'll have 12.4's no problem.

What are you running for front suspension? Your're gonna be going quicker once those 60s come down :)

Stock springs and sway bar. I have CE drag shocks set at 80/20 front and 50/50 back. I was thinking of trying 90/10 - 60/40. I was also reading some of the guys are trying 0 preload on the drivers side with a 1/4 or so on passenger and calvert says to make adjustments in 1/16 turn increments. It's kinda hard to tell exactly when they start to preload. I was using a credit card to slide under the bolt to feel when it was contacting the spring.

Ditch the sway bar and get some Trick springs. Unless the car wasn't leaving straight, adjusting the Caltracs unevenly wouldn't have any benefit.

[bowtie0069]

My question would be what tire are you running? All the suspension tuning in the world won't get a bad tire choice to work. Is it a street tire? Sticky street tire? Radial? Slick?.................

M/T ET Streets, 235/60/15. Launching at 4100 RPMS off idle. Last season I was pulling 1.69 to 1.75 60's with those tires and old slapper bars. This winter I had the trans rebuilt and added some new heads. Couldn't hook the first time out this year (more torque I figured) and that's when I put on the Cal Tracs. Last night was the first time with them.:)

Some of the guys that were out there were saying the track conditions weren't very good.

[DEL]

I'm convinced the track was weak. The cold weather doesn't help either, but I saw a lot of cars there that I'm familiar with, and none of them were hooking up.

I definitely agree that you should ditch the swaybar, it's a "free" upgrade :) and it will help.

[1ARUNEM]

Same tires from last year? They could be dead...

[Repointer]

Same tires from last year? They could be dead...

I thought about that. They have about 65 or so passes on them plus street time to and from. Aren't down to the wear indicators yet, but are starting to get close.

My 60's weren't dropping at the end of last year though, staying real consistant in the 1.70-1.75 range right down to the last night. Maybe sitting in my garage this winter affected them?

[DriveWFO]

Chris,

Maybe you could try some of this stuff out. It's made by the guy that will be doing my port/valve work:

[66IISS]

We use that same stuff on Auto-X tires after they've been sitting over the winter. Soft tires like to get hard with time.

It works well, but wont make 'em new, just make 'em a little bit better for a few runs though.

It does work though!

[Repointer]

Here is the video uploaded properly, camera man needs work.:rolleyes: I hope to get a better one tomorrow.

Last week tried the 1.6 rockers and had no gain. Gonna try running them just on the intake side. Also the plugs were too cold, going one step hotter. I'd like to see 107MPH. Also gonna buy new tires after this outing, so might take a break for a few weeks and let the finances catch back up.

[bowtie0069]

I'd like to see 107MPH

Me too, I've seen 106.65, but then mine was in the 1/8!

That's a whole different ball game.:eek: Maybe next year if I decide to get more serious 1/8 and 100mph might be mentioned in the same breath. I doubt it though.:D

[Repointer]

No 107mph yet, but I'll take it. She seemed to like the 1.6 intake, 1.5 exhaust. First run in the middle of the day heat, it would've run quicker in the evening. I let a friend use my tires after that and didn't get enough time to test the hotter plugs; next time.

60' - 1.704
1/8 - 7.857
mph - 85.92
1/4 - 12.460
mph -106.20

Here's a video of the launch. Were still working on the camera man.:rolleyes: I didn't think it was gonna run this good or I would've had him tape it all. The guy in the Ford Lightning ran a 12.96@105.84. He beat me a few times last year.:p

Holy Crap Chris!!!!!!!! Those are much better times!! Glad to see you getting it worked out:D

Thanks Dan. I'm running Dave's old converter, Summit 3200. It flashes to 4100 in my car, but that's just fine with me.:)

Great job their Repointer :) We just gotta keep chipping away :)

[Ron Slabaugh]

I really like how the whole car jumps in the air when you launch. It's interesting to compare that to others with no traction aids. They seem to squat in the rear much more.

How much converter slip (percentage) do you have going through the lights at 106 mph?

Running it through the TCI calculator with 1 inch added for tire growth I have been figuring probably between 6 and 8%

I don't really know if that's good or not.:o Someone else brought up a question about converter slippage. I am gonna start doing some more reading on the subject.:)

well this calculator says you should be doing 108.87 at 5250rpm with 3.73's and a 26" tire

http://www.angelfire.com/fl/procrastination/rear.html

Not sure what that means if anything for ya:)

[66chevyIISS]

that doesn't factor in slipage

[DriveWFO]

Chris, using the converter slippage calculator on WallaceRacing.com (http://www.wallaceracing.com/converter-slip.php), I came up with just under 3% slippage...seems kinda low to me.

MPH: 106.2
RPM: 5250
GEAR: 3.73
TIRE CIRCUMFERENCE: 81.67"

Ya the figure I came up with shows a 2.51% speed difference....(convertor slippage possibly?)

[Ron Slabaugh]

There are many opinions on "ideal" slippage. You're probably losing performance if it's over 10%. 3-6% indicates a pretty efficient setup. I'd be surprised if a budget converter that flashes to 4100 rpm is only slipping 3% at 5,250 rpm. Wonder if actual trap rpm is a bit higher? However, it does not appear you're losing performance with that converter.

I ran that converter before Chris bought it off me. I had calculated 8% slippage when it was on my car.

would the weight of the car (and driver:rolleyes:) effect the slippage...his car should be lighter then yours:confused: :)

I think Chris's race weight is a good bit lighter than mine, so you would think it would slip less.

thats what I was thinking.....so possibly the 3 percent is right...I dunno just speculating:confused: :)

[Repointer]

I think the tach is fairly accurate, but it is an old Autometer from back in the day. A new 5" tach is gonna be on my short list of things I will be getting soon. Last year when I changed from the TCI 2200 converter to the current one I don't remember trap RPM going up by very much at all.

My weight with driver is around 3200 by the truck scale down the road.

[Repointer]

Looks like some posts got deleted, oh well. Here's the post from the other site for those who didn't see it.;)

Well..new best, but barely. Brandon (novas4life) came out and let me run his skinny pro stars up front. Thanks again Brandon.:) I dropped about 60lbs unsprung total. Only got two runs in before it was called on rain.

60' 1.715
1/8 7.866
mph 86.31
1/4 12.446
mph 106.81

Kinda puzzling that my 60 and ET stayed almost identical while my MPH went up 6 tenths. I couldn't feel any spin, but the car just didn't feel like it was pulling as hard as usual. The only thing I can think is the air. It has been very muggy and humid here all week and was no better last night. It was actually sprinkling on that run. Not quite sure how the air affects times though. Well they are closed until the 23rd, so I'll have to wait until then to try again.

[Repointer]

Very busy the last few weeks. Did manage to get the new fronts installed this morning. Still looking to run 107 in the cooler/better weather tonight. In the 90's today, at least it's a dry heat.:rolleyes:

Might step up the plan for the car... paint, interior, engine, cage:eek: , will be decided soon, might have to end the season early to start the tear down.

Here's a pic since the last one got deleted. Minus the male model.:D

[Ironman]

I feel your pain. I was hoping to reach high 11's with some recent changes. Ain't happening for me so I pulled the motor to freshen it up and make a cam change, probably take some duration out of it.

I saw Ron out there, he hit the 9's his first run and was told he was done for the evening. I told him about this site, he said he might check it out.

[DEL]

Just as impressive as Ron's 9 second slip was his driving that thing to the NW Nova club meeting the next day. I'm guessing its only about a 20 mile drive for him, but it was 100 degrees out!

I've got a complete cheater kit, as well as a complete Mallory fuel system (it's still new in the box) I could be tempted to sell it all since I want to go with a turbocharger anyway :D

I'll let you know. After I lost that bid I gave it some thought and figured maybe I was just gonna go with a new motor when I paint the car. I don't know...I'm worse than a woman trying to make up my mind.:p

The Chevy dealership called the old man today to let him know that his 2007 Z06 Vette should be here in August. That means I have to be in the 11's before than, no way I can let him beat me. I don't think he can pedal one of those in the 11's, but if he springs for drag radials I could be in serious need of the NOS.;)

12.26, that is right on the money for a 108mph run. That is so awsome.Great job.

Moroso electric drive kit is about 40 bucks,a relay and harness from a car stereo place is about 8 bucks and a toggle switch is about 4 dollars. Really cheap horse power.

[DriveWFO]

Sweet times Chris!!!! :) At least your car is running right now!

[Repointer]

BTW,

I think I got the tach working correctly now and with the fan off last night I was traping around 5800 at 108mph. I calculate that to be around 12% slippage with no tire growth. Sound better? Is that too much?

Any estimates of when you'll be back at the track Dave?

Well July is pretty busy for me and since I'm building the motor myself, I need to take my time and make sure I'm doing everything correctly. So....probably sometime mid-late August :confused:

[Ron Slabaugh]

Did you have any problems staying cool running with no fan at all?

12% slippage @ 5,800 rpm isn't bad considering your stall speed. You're probably not leaving much on the table with this converter and your current powertrain configuration.

The electric drive kit is an option, but I think I would have to move my alternator to the drivers side. I've heard it's worth 5 to 7 though. My next "free" HP gain will be from getting rid of the power steering.

Hey Gentlemen, Ive got enough 'street' miles on the new rear suspension/rear end. I'm picking up my new driveshaft at 8:00 am tommoro.I'll weld on the saftey straps to the ladderbars,set the pinion angle,change oil,plugs and such and be ready to rock.
Looks like we'll have a good time on Sat. I'd like to run a 12.2 or 12.1. If I can get the bars and shocks dialed in.
See ya'll there

Repointer, Watched you run tonite you did great your car leaves the line hard:eek: . I did not know it was you untill I aked if Chris was here and Brandon sait it was the light blue 67, other wise I'd of said hi. You have one heck of a car, hope you get to your goal you are soo close now.

Thanks. If your out next time stop by and say hi. There is plenty of time to BS in the staging lanes :rolleyes: , they were moving sooo slow.:)

Getting closer!:D She liked the new manifold and was pulling REAL hard on the top end. Man it feels like it's been running strong lately. Three in the 12.1's and the best was...

60' - 1.66
1/8 - 7.63
MPH - 88.66
1/4 - 12.10

P.S I made it home alright, Rex followed me to my shop and then gave Tara and I a ride home. I knew I was going to loose that alternator at some point,but I didnt think I'd pitch the belt to another galaxy. I highly recommend Optima batteries. Ran with headlights,water pump,and fan on the whole way back.

Shoot, a 10 degree drop in outdoor air temp and you'll have your 11.99 - or better. Good looking cars guys! I enjoyed the videos.

It was a real blast running with two other 67s all night. :D :cool:

Hey Brent and Brandon,

Hoping to go out to PIR this Sat. if any of you guys are interested. No big changes for me, different oil, some race plugs, take the tools out of the trunk this time:rolleyes: and see if I can drop the extra .11. If not power steering is next to go.;)

If you want those plugs (AR73) let me know Brandon. They only have a few runs on them.

Did you make it up to the NHRA races Brent? We left early Sunday and were there from about 11 to 5. It was VERY warm, but very cool.;) The quickest run I saw was only a 4.65@320 something:eek: :eek: .

I'd love to race this weekend, but this is a little girl treat weekend for my daughter Allison. We're taking her to the beach for the first time on Saturday. It should be fun. I wish I could race also.

I made it up to Auburn on Saturday. Too F'in hot to stay very long though. I watched enough runs to whet my appetite for speed though. :D

Hopefully August will be a good month for concentrating on Nova stuff. Cross your fingers. I'll be rooting for you from afar.

[Repointer]

Yea, the little ones have to come first. I got my 6 year old a shirt from up there, now she's all excited to wear it out to watch daddy race.:)

It was HOT. All we could stand was about 45 min at a time until we had to go cool off somewhere.

Just let me know when you plan on going again and I'll try and make it out there.

Exactly my point. My oldest takes some Hot Wheels and Monster Trucks with him and plays in between rounds. Sometimes when it's time for dad to make his next pass down the track, he gets to hang out in the announcer tower. He thinks that some cool shi*! :D

Yeah, 14mos old is a bit young to be exposed to racing carcinogens. Maybe when she's a bit older. Also, I can't convince my wife to join me at the track, and I don't think NHRA rules allow you to make a run with a child seat in the back. :D

I still have some fiddling to do with my car before taking it out again. The weather needs to cool off a bit before that can happen too.

Chris, I'll let you and the other NWNova guys know when I'm ready to run again. Possibly next weekend......

if they allow it, try deep staging and pulling out everything that can come outta the car...that should get ya to the 11's before you jump on the NAWZ bandwangon...:)

I have been shallow staging. Suppose to give a little bit of a running start for a better ET. Reaction times are a little inconsistant though, but I did pull a -.001 last night. Almost got a perfect light patch.:p

well you could try shortening the track a bit by deep staging to see if that works..but ya I'm heard of the shallow stage running start too;)...where is your battery? Possibly if it is under the hood right now moving it to the trunk might help with weight transfer and give you a slightly better launch...hey it all helps in the end:)

It would be cool to pull one wheel, but I don't know how far away that is.

Believe it or not, Deep staging slows you about a tenth. You're reaction times are more consistant and quicker when Deep, but you slow up at every incremental of the track. Many footbrake bracket racers deep stage, b/c they just want to have consistant lights and don't care about ET.

[Pick]

Deep staging does slow you down a little, but it doesn't make you any more consistant. That still boils down to driver and car, not where you put your front wheels. Most people who deep stage do so because their car reacts slow and they want to leave on the last yellow.

Reread my post, I stated that Deep staging makes your reaction times more consistant. Most people who deep stage are footbrakers that run Pro. Yes, there are people who deep stage that do so b/c they're car just doesn't react quick enough as well. In Division 1, most pro/footbrake cars Deep stage. There are only a handful of heavy hitters that go shallow.

I understood that you meant reaction times would be more consistent if you deep stage, and my reply was meant to answer that. I wasn't referring to your et's being more consistent. Deep staging might help some drivers react more consistently because of the way they drive, or the way their car reacts, but there are no physical reasons that deep staging will make your reaction times more consistent.

It's always a good thing to try though, because you never know, it might help you. If you're more consistent deep staging, then deep stage.

Your point is well taken, Novacain, and it's good advice for folks to try it. :)

[Dan_Lebherz]

Hey Repointer, those are some great times. Congrats!
Now, I'm Jealous.

I deep stage.... my car left realllll sluggish with the 307 and stock converter. Much easier to cut a light leaving on the last yellow than trying to jump in between bulbs.

Kev

[novaracer1]

I think we need to remember that Repointer is looking for ET gains, not consistant reaction times, so deep staging will only hurt his efferts. Go as shallow as you can.

There it is!! Had to resort to the 1" carb spacer, took a little away on the bottom end, but gave me about 1 mph on the top end, good enough. Battery died after that and I was done for the night, no complaints here though.:D :D

Thats a fairly simple set up....just goes to show you dont need solid rollers and what not to run great numbers...

Looks like I got some work to do if you can run those numbers with that mild set up!

Kev (The pep boys manager told me my nova was "down right radical" :D )

[Repointer]

Thanks again guys. It is a pretty mild set up, plus all steel body, the only lightening to speak of is removing all the seats for a plastic race bucket.

Brandon was telling me that those Flowmaster 40 series are pretty restrictive mufflers, not wanting to spend a lot more money until I figure out what route I'm going now with this car, I was thinking about uncorking the headers and just tying the exhaust to the frame connectors for one evening at the track? I wonder if it will help; I know it will be loud.:D

[novaracer1]

What does the car weigh?

[Dan_Lebherz]

Chris,
I have done as you suggest several times always expecting a new low ET. Usually, there was some other factor like weather, headwind or something else going on the ruin the effort. My best ETS have alwasy been set corked.

[Repointer]

What does the car weigh?

I'd guess around 3150 with me in it. I gotta go weigh it again though since swapping some stuff around.:)

[John65ss]

That is awesome!

You know... I was planning a 406 for my car (long term plan), but you Northwest guys (and Dan Lebherz) are making my wonder if I really need anymore than 355 cubic inches for a quick, streetable 1st gen Nova.

I was thinking a 400ci as well, but this makes me think i have some miss mached parts in my combo. I have quite a bit more hi po parts so to speak, then repionter, and i'm running the same numbers. I've been told that with my cam and compression I should be running a single plane intake and about a 4-4500 stall converter. Didn't really think much about that, but maybe the're right.

Anyway, congrats on some excelent ETs repointer. Sounds like you got the right setup.

You got enough MPH for 11.70s. With that much duration, you need more converter.

Sounds pretty good to me. If you were 100lbs or so lighter you'd be looking at 115 and change. I don't know if you're running a carb spacer on that air gap, but a 1" picked me up by over one MPH and seems to be pulling even harder on the top end now.

What kinda 60's are you pulling?

I love the pic with daylight under one wheel.:cool:

Repointer - is that a 1" open or 4-hole spacer?

Repointer - is that a 1" open or 4-hole spacer?

Just a cheap 1" open bought at the local auto parts store for under 20 bucks. I also was looking at the HVH line of spacers, but most all the comments I could find regarding spacers said most guys saw no real difference between the different types, it seemed to be more the height. I might try a 4-hole next time out just to see though. :)

I have a 1" 4-hole spacer and a 1" open spacer that can convert to a 4-hole with an insert. I've been running the 1" 4-hole with a 1/2" nitrous plate. I'm gonna try out the 1" open spacer soon.

[nova10sec]

I spent a good bit of time on the dyno with spacers. A 1" open gave 11hp. A 1" 4 hole hurt by 4hp vs. no spacer. Keep in mind that this was on top a super victor that I believe is already 1" taller. So a 2" on a victor should be equivalent.

Here is an interesting note, even though it made more dyno HP, at the track w/ or with out, I et'd the same, and same mph. I would conclude that it may have only shifted the power band (lost some lower, gained some up top
).

Definitely shifted the power band up for me. For the record here are the three runs.

No spacer, Aprox. 6000 RPM shift points

60' - 1.655
1/4 - 12.12
MPH - 109.63

Spacer, Same shift points

60' - 1.680
1/4 - 12.05
MPH - 110.13

Spacer, Aprox. 6200 RPM shift points

60' - 1.676
1/4 - 11.98
MPH - 111.33

Battery died after that and no more testing. I think there might be a little more there with more testing of shift points.

A friend talked me into going out to the track last night (I was planing on the local car show on Sunday), anyway I decided to switch from 76 to 78 jets in the secondary(650DP). No big deal. Headed out to the track and died at the first light, just wasn't running right. Got gas, headed back home to fix the problem, got there and it seemed to have fixed itself.:confused: Looked it over and everything seemed OK. Went out to the track, two runs, serious bog out of the hole and just not pulling like it should.

60's were 1.73 then 1.76 and 1/4's 12.08 and 12.16 both at 109.

Float level, accelerator pump, no leaks, all checked out good. That was the only thing I touched since last weekend. I've done jet changes before and never had a problem like this. Any thoughts?

[Pick]

If you pulled the jets out of a box with lots of jets in it, you might double check the numbers on both jets. Sometimes they don't stamp that number on them too well and I've misread them before.

Yea, I pulled it apart and double checked this morning. I ran those 78's last year, they just didn't help any. I thought with more power now the motor might like a little more jet on the top end. They only thing I can think is the reused gasket got tweaked enough to partially cover up the accelerator hole in the body?

BTW- I saw that 1.46 60' in the other thread.:eek: That is awesome, I thought my 60's were pretty good. Nice job.:)

Well, I've never had a gasket do that, but I guess it could. Like you, I can't imagine that a 2 number jet change alone would cause a bog. I changed to a set of reusable gaskets and they have been nice. I've had the bowls off several times and they reseal every time.

The 60's in this car have surprised me - but it's a good surprise! This winter I'll be switching to a PowerGlide and CalTracs. I'm curious to see how the 60's will be after that.

[Repointer]

Have you starting tuning your high-speed air bleeds?

Nope. I'd have to learn how first.:D

Up until last night though I never had this problem. It was always just "right there" on launch. Plus the way it was acting, I could tell something wasn't right as soon as I left the house. I should have known it wouldn't just magically fix itself and saved my money for when I figured it out.:(

The last launch was so bad my brother thought I had got on, off, and back on the gas again.:)

[LSWHO]

Cal-Tracs Installed. Now I have to learn how to dial them in. 5 runs and all spinning out of the hole. If I can just match my 60' from last year I will hit the 12.4's. The last was the best.

60' - 1.994
1/4 - 12.806
MPH - 106.08

I tried these settings in order, the bottom hole 1 full turn, 1/2 turn, 1 1/2 turns, then switched to the top 1/2 turn and 1/4 turn. I had someone my weight sitting in the car, but it was dark and hard to accurately count the turns.

What is your pinion angle at? What did you use your baseline at?

I have thought about that. Even if you're not spinning, there's probably a way to better 60's with a more efficient launch. Might give me something to check into after I figure out this new found carb problem.:beat:

[Repointer]

New bowl gasket with 78 jets, still bog, put back 76 jets, still bog. Nail the accelerator from a 5mph roll and the car just dies. Checked the basics, timings right on, vacuum advance is working, pulling 13"-11" vacuum in gear. I'll be checking into it more thoroughly as I have time, if you have any ideas feel free.:)

[69NovaSS]

is this a VS carb? Could it be that the secondarys are opening too fast causing a momentary lean condition until the motor catches up?

[DriveWFO]

Don't think the jets would have anything to do with it falling flat on its face when you nail it from a slow roll...I'm thinking something with enrichment circuits.

[Repointer]

It's a 650 DP. Changed back jets cause it worked perfect with the spacer and 76's, then last weekend I put in the 78's (only change) and then it had a serious bog. You can see in a few posts back. Jets make no sense to me, I was just going back to what worked before and now it doesn't. Gotta figure out what changed.:confused:

Gotta run guys, good luck tonight Dave.:)

BTW - I stopped by the truck scale while out testing last night. I guess I took off more weight than I thought. 3050lbs w/driver.

[69NovaSS]

It's a 650 DP.

Ok then forget everything I just said....lol:D

Have you opened the throttle all the way without the engine running to see if you're getting a good stream of gas out of the rear squirter? Sound's to me like that rear pump may have quit working, or a piece of trash found it's way into the squirter circuit.

Shoot, it ain't about my ideas, it's about getting you running right again. :D It sounds for the world like you're starving for fuel when you nail it, but why??

Are you using the big vacuum port at the back of the carb under the rear fuel bowl? If not, is the cap still in place and sealing? (and the other plugged ports as well)

Yep, running the PCV off it. All the other's are plugged or being used. Everything's just how it was before. Vacuum is the same as before, so there appears to be no leaks. I should get some time today to go out and look over everything real good and see if I can come up with any other idea's.:)

[Repointer]

Looked everything over, come up with nothing. I gave up trying to figure out what changed. Just going to fix the bog. Pulled the carb apart, cleaned bowls and metering blocks, checked the dist., retaped the vacuum ports. Better...but still bogs. Pulled the spacer..even better yet, but still slight bog. Squirters are 28 front and rear. Gonna try Pick's advice and start going bigger on rear. The car seems to run good all around except when I nail it real hard.

You know you have a little power when you pitch it sideways on the street at a 15mph roll in second with Drag radials on.:D Gotta love that converter.

When I had my tranny rebuilt this last winter the converter was flushed and thats about all I know about it. I got no complaints though leaving at 4300rpm. Maybe I'm pulling a wheel also since everybody else around my time is.:p I just gotta work getting a camera man to find out.

It seems to be pulling real hard on the top end and I can't image I have much more than 111 in it even with a different converter.:)

Oh BTW - I shouldn't even open this can of worms, but I'm still running the original stock fuel pump and lines with no regulator. I have 3-5 psi at idle and a steady 4 psi at 3k. Just been going with the "if it's not broke don't fix it theory".:)

Yeah, maybe so, but there ain't a hotrodder I know who doesn't mess with perfectly good working stuff just to see if there's another .01 to be shaved off his time. It's the nature of this chronic disease.

[Dan_Lebherz]

Just something to check and double check. I have had this happen to me. Everything is working fine but for some reason you remove and replace the carb and expect everything to be exactly the same because you'd swear you didn't change anything. Only thing is now for some reason you are no longer getting full opening on the throttle blades. Its because when you had the carb off, some gremlins came along and changed the adjustment so that you are only getting 3/4 throttle now.

I once spent 4 weekends trying to figure out why my car slowed down only to find that I was only getting 3/4 throttle.

Either that, or b/4 you had a tail wind and now you have a head wind.

either will certainly do it.

Still makes no sense to me. I just gave up on trying to figure out why and just fix the problem....seemed to work.:)

I tried some higher shift points last night and seemed to be floating the valves at around 6300. I'm running the springs that came on the heads, the Z28 style .550" ones. Was wondering if it would be worth it to put on the comp springs that were recommended with the cam that's in there. (They are still on my old heads).

Good looking car. Looks like it hooked up and ran good! Gotta love them kids!:)

[Repointer]

Pulled plugs tonight looking things over. #2 is wet, not dead, but definitely not firing like the others. Compression is good. Should be something simple then.

Last night first run was with the 78 rear jets. 12.00@110.5

Then I changed back to 76 rear and ran a 12.14@108.4

Didn't make sense that it slowed that much, cause I ran the 11.98 with the 76's, but it was laying over on the top end big time last night.

Once I get #2 fixed it looks like I have a date with the track for next weekend to try and break a record with the bigger jets.;)

[Repointer]

Been too busy to mess with the car much lately, but here is two pics, the first is of #1 and #2 right after driving home from the races the other weekend. The second pic is after putting a few miles on them around town. #2 just has a heavy grey ash all over it? I have a new cap and rotor and leak down tester coming tomorrow.

I did some pretty extensive testing between the 104's and 103's and the colder ones always gave me more MPH, so I stuck with em.

I'm more worried how #2 looks so different from the rest now, even the porcelain is covered in a hard gray ash? It's kinda hard to see in that pic.

Hopefully I get time to get out there Saturday and see what happens.:)

[DriveWFO]

You really need to run the car WOT and shut it down immediately and coast to a stop, then pull a plug or two.

[novas4life]

Too bad I missed you last week Chris. I was on vacation,so I ran Wend. Night bracket. I got put out 1st round but got in 8 runs. I ran 2 7.70's(1/8th mile racing). Then I ran Friday night and turned a 12.36 and a 12.38.

If compression is good, kinda makes me wonder if it isn't a bad valve seal. Granted the heads are new, but at least it would be fairly easy to fix.

Here's a pic. Not as bad as I thought. Broke one piece of the spring, chewed up the seal and shim a little. Everything else looks good. I'm putting the Comp springs on for sure now though.:D Should have done that before.:o

[Ron Slabaugh]

You were definitely floating the valves. Notice the pattern on the valve shim and the overall damage? There is no doubt.

How do the valve tips look? If you examine them closely do you see a star shaped pattern? That is another sign of valve float.

I'm sure installing the Comp springs will help. However, I remember a dyno test (magazine article) testing the extreme energy hydraulic flat tappet cams when they first came out. Using the entire cam kit, this particular SB chevy was floating the valves just over 6,000 rpm. The magazine promised to run a followup article, but never did. I imagine Comp's advertisement fees had something to do with this.

Enough conspiracy theory. You might consider a set of Comps beehive springs for your application. The spring/retainer combo is much lighter in weight, which allows use of less spring pressure. It's close to impossible to float these compared to a standard spring.

So far the tips look good. I think it only happened for a split second twice on the top end. I have the 981 comp springs that were recommended for this cam sitting on my old heads. I was thinking of putting them on?

The ones that were on the RHS's were 1.800 installed height, and the 981's are 1.700. Is it normal to have to shim em up .1 or so. Also the valve pockets are 1.500 on the new heads, so I have to get some different shims also??

Does any of this sound reasonable?:o

[Camgrinder]

As badly beaten up as the shims are, I would also replace the valve locks (keepers).

[Ron Slabaugh]

I'd agree with replacing the keepers.

You might be able to purchase shims where the ID will center on the valve guide and the OD will curl up to hold the spring in place. It's normal to shim to achieve the specification recommended by the manufacturer.

I've been following your success this year and there is no doubt you want to maximize the potential of your combination. If it were me (and this is just my opinion) I'd install a set of beehives with matching hardware capable of controlling that valvetrain to 6,500 rpm. I think your motor with that cam would pull nicely to 6,500 rpm and your car would go faster.

[Repointer]

Well I gave up earlier trying to get something fixed for this weekend, so now I can sit back and give it some thought.

Don't know a lot about the beehive springs, but will check them out. Maybe call Comp for a recommendation about which ones to run cause I would have no idea? :awkward: Maybe you do. I would like to figure about how much it will cost me.

My second thing is how much more money do I want to spend this year. The motor will probably be coming apart this winter for atleast a short block change and if I get to 11.49 the car will have to go though some upgrades also.

The 981's are already paid for and might get me though the year, but 6500 RPM's with the proper springs sounds like a receipe for fun.:D I guess I'll know more when I get some pricing.

Thanks for the help.
Chris

[Repointer]

OK Ron, I've been up since 5am obsessing about this as the wife would say.:D

Maybe the 26981 or 26915 beehive springs? From what I read most guys say they are worth around 500 more RPM. They only knock is that since they are a single spring if it breaks could be trouble.

Here's another pic, the spring pocket is 1.500 and the guides have threads with the threaded type valve seals. Distance between pocket and retainer with no shims is about 1.800

I have a family barbecue to attend to today, but will be looking into this more tomorrow.

Chris; Crane makes a stock dia. single spring with damper that is made from H-11 tool steel...its good for roughly .600" lift and I have them on my 041's and I have been to 6800 before with no issues at all(solid lifters)....they seem to work really well...just a thought

[Ron Slabaugh]

Chris - read this for some good info on beehives.

http://www.popularhotrodding.com/tech/0607phr_camshaft_basics/retainers.html

I'm not certain which spring would be best for your application. You might consider giving Comp a call.

Valvetrain control in a hydraulic cammed engine is extremely important. Once you start to float the valves, the lifters pump up and power drops off in a hurry. It may not be enough to feel, but you'd certainly see it at the track.

[Repointer]

Thanks for the info guys. I'll be reading tonight.:)

Another thing is some of the rocker arms and balls are discolored (heat).
The one in the pic is the worse case. Doesn't seem to be lack of oil, there are no groves in the studs, but you can see some studs with a slight mark on them. What do you think? How would you gain more rocker to stud clearance if needed? Thanks.

Yep, I think it's the sides the are fairly tight. I had to use Proform studs cause the other ones would bind on the bottom.:(

[69NovaSS]

I'm pretty sure you could open up the sides of the slot a bit with a die grinder(or something simular)....I'm sure it wouldn't take much clearancing to make a difference

[Dan_Lebherz]

I you are talking about opening up the hole in the rocker, you may want to be careful about that. Are those stamped steel? If they are, they are probably heat treated. Certain types of heat treating primarily affects the surface hardness. If you remove the surface, you remove the hardened part.

I am running the small diamter Crane tool steel springs on my Vortec heads. they sell the springs and retainers together. Using the stock keepers, they are supposed to provide something like an additional .040 of clearance between the top of the seal and the bottom of the retainer. Using the Crane keepers actually reduces this clearance.

this is a quote from the book "The Step-By-Step Guide to: Engine Blueprinting" by Rick Voegelin

[Repointer]

I was checking this out last night and am beginning to think its an oiling problem. I checked clearance when I installed them and everything was OK. I didn't have any problem with the stamped steel ones overheating.

I saw I'm not the only one to have a problem with the Comp Magnum roller tips overheating. The pushrod holes line up when sitting there, but I don't know what the geometry does to them at high RPM's? Maybe the valve float had something to do with the oil not geting through? Maybe the crappy springs that came with the new heads, or the way the guy installed the springs, but that doesn't explain the stamped steel's working before?

A few look good, but the majority have definitly been overheating on the bottom of the rocker and rocker ball. Here's one guy talking about his problem with them.

http://www.chevelles.com/forums/archive/index.php/t-23011.html

[Repointer]

I checked retainer to valve pocket measurements on the pass. side (not removing springs on the other side until I get a real spring remover) and they are all equal except the #2 intake (broken valve) which was about .015 more than all the rest. 1.815" for that one.

He had the same shims on all the springs, so either this one was like this from the beginning and wasn't shimmed right or something changed to open up that one up .015.?? I don't know if this contributed to breaking that spring.:beat::(

[Repointer]

Hey Ron,

Been reading up on the Beehive springs, man they sound like the hot ticket. Gonna call Comp tomorrow and talk with them about those and the rockers. Looks like I'll be spending some more money to go faster. The track is closed this coming weekend, so should give me plenty of time to be ready the following.:)

[Ron Slabaugh]

I think if you go that route there is nothing else you can do to optimize that combination.

Do you have any winter plans?

Yep, that will be about as far as I take it in this form. I think with the springs, hardware, and some new tools, the spray will have to wait until next year.;)

As far as winter plans, I don't know. I'm gonna be closing in on that 11.49 with a new short block, so thats gonna mean changes if I want to still run out there. Not a big deal over the winter but I don't know if I can run another summer with that ugly paint though. If I do decide on the paint that might put me out of commission for a little while. We'll see.:)

Talked with Comp twice.

Called back and talked with another guy and he said that Comp has them in stock (more expensive) but gave me another spring he thought would work just as well. 26918-18 with all the hardware and he also said I need to use locators.

The first guy also said that my rockers are definitly overheating and he said because of my lift and rpm I'm on the ragged egde of what the roller tips can handle. Maybe?:confused: He didn't think there would be any problem with them in the near future though.

Looking good! Those should do the trick. Let us know how they work. I've always wanted to hear a testimonial on the beehive springs that wasn't in a magazine.

What kind of spring compressor did y buy, my springs were a nightmare. Had to stop half way couldnt get the keepers to bust.

Here's the one I got.

What does that tool do that my glorified pry bar doesn't?

Well it does the same thing, I used the "glorified pry bar on the first set I did. With this tool, much easier to compress the springs, don't tear up your hands on the pry bar, it locks in place with the springs compressed so you have both hands to remove/install the locks. One of the better 40 bucks I've spent.

I bought one like that too. I was able to change all 16 with the heads on the engine in the car. For a few I had to disassemble the compressor so I had enough room but it worked very well I thought.

Heading out about 5:30 tonight if the weather is gonna hold. Tried last night, they said they were running, but I started getting rained on a few miles from home so I turned around.:(

I'm headed out there too,Chris. Keep your fingers crossed for the weather.

Not what I had hoped for, but I did back up the 11 with two 11.96's. Tried jets, timing, and different shift points, best I could get out of five:

1/4 - 11.96
MPH - 110.74

I was carrying an extra 30 lbs with gas and stuff so maybe there is a little more there, but not much.

[Ron Slabaugh]

I was hoping for 11.90, but 11.96 is nothing to sneeze at. It is interesting that your ET decreased 0.02 seconds despite a loss of 0.5 mph.

I'm certain you've resolved any valve float issues. Based on 1.78" installed height, the Comp 26918 beehives should give you 135# on the seat and 325# on the nose. You must have been thinking ahead for that future hydraulic roller or solid flat tappet cam:D

That motor has been raced a lot. Is it possible the shortblock is getting tired? Have you looked at compression and leak down lately?
