Went to the track for the first time since I got the motor running in November. First time to the track for me in 18 years. What a blast!! It's fun when everything works. I had no idea what the car would run. I was hoping for some solid 11's but wasn't really too confident. I'm feeling good now. Here's the numbers. Now of course, I want to go faster.

1st run
1.638 60ft
7.402 1/8th
91.86 mph
11.71 1/4
113.13 mph

2nd run
1.619
7.376
92.01
11.669
113.83

3rd run
1.633
Then I went 1st to neutral. Still not used to the reverse valve body. Oops! Thank goodness for rev limiters.

4th run
1.627
7.426
91.71
11.721
113.59

The last run I tried raising my shift points and I think it hurt me a little. That's okay I'm glad to shift low and go just as fast.

I didn't do any tuning. I was just trying to learn how to drive the car and get used to going down the track. The car handled great. Smooth as glass all the way down and felt like it was pulling all the way through. I pulled a plug once just to check it out and it looked pretty good. If anything, it may have been a little lean but not much.

So next time out I'd like to start playing with the tune a little to see if I can get a little more out of it but I'm not sure where to start. Any suggestions on a good plan of action?

Just wanted to post my results because I feel like I was fairly successful for my first time out thanks to all the reading and advice I've gotten off this board. Thanks for all the invaluable info along the way.

Looks good to me......That 60 ft with a mid 11 second @ 113 tells me there is more in it... Top end is struggling a little bit @ 113. :yes:

More info on the car set up.
Suspension, shocks, trans/ conv. tires/slicks? Motor BBC or SBC ?

Any pics or video?

Well done! :yes:

wow, congrats. getting into the 11s first time out means something is working, and its definitely something to be proud of.

do you mind sharing your combo?

Thanks for the positive comments. Yeah, I also thought the mph was a little low. I guess that's where the tuning comes in. Here's the specs on the car.

70 nova, all steel, full interior w/bench seat.
Moser 12 bolt w/3.73 gears
weld in frame connectors
solid body bushings
caltracs, top hole, 2 flats of preload

The front end is all stock, swaybar removed, 6 cylinder springs, everything as loose as I could get it. caltrac 90/10 shocks. The front end has a good 5 inches of travel.

The engine is a 383
zero decked 010 block

th350 trans full manual reverse valve body(thanks to Jakeshoe)
Edge 9.5 inch 4200 converter

Am I forgetting anything?

I was leaving at about 1500 to 2000 rpm. Not really sure where the converter was flashing. Too much going on for this rookie to pay attention to that. Any advice is appreciated.

 

[johnh]

Slicks or radials?

EDIT....sorry found that answer in your above......


Did the car spin at all, or hook up and go...

 

[mdla]

Friends at the track said it was hooking and going. No spin. They also said I was getting a little air under the tires. No pics darn it. I need to try to watch the tach leaving the line. I'm not sure the converter is flashing as high as I'd like.

Here's a little more info. Since we can only get 91 at the pump around here, I was running VP unleaded 101 fuel I got at a distributor right around the corner from my house. I know with my combo I can probably tune it to work on pump gas, I just didn't want to risk it my first time out. Could the higher octane actually be hurting me? Also what about the 38 degrees of timing?

Thanks againg for the input.

mdla..... I just sent you a PM. check your inbox....:yes:

 

[fasteddie]

Those are some impresive times for first time out. You better be careful or soon you will need a rollbar!:yes: Keep us informed on future progress.

 

[mdla]

Yeah, a roll cage is on the list for this winter maybe. Better safe than sorry. Of course the extra weight isn't going to help. I need to find a way to offset it.

Weather permitting, I may try to go back next Sunday and see if I can do a little tuning. The quest begins. And I told myself if I could just run some 11's I'd be happy. Hah!
