I'm gonna assume its about a 4000 stall on the converter.

Man that is really close to mine: 383/AFR 210, 10.5 compression, Lunati .600 solid roller(255*/263*), Victor Jr. w/2" spacer, 850 Quickfuel carb, 4000 converter and a 4.11 gear.

I haven't ran mine at the track, been driving if for 3 years, it's been ready since I cranked it 3 years ago, I just haven't driven it to down to the track. I know it will run at least a low 11, but should do a little better than that.

 

[Deeznuts]

What size and stall speed is the converter? Do you know how much the car weighs?

 

[66II]

Ideal conditions and the car setup right it should do 10.90s-11.0s

 

[bracketchev70]

11.30’s at 118.

 

[Ryanjoseph1994]

Well I have a 3000 stall right now trans and motor ain't in yet I'm thinking going to 3500stall if I were to guess the weight probably 3200 possibly 3300 I don't know what the 74s weighed off the lot but I switched the whole front clip over to 72so impact bumbper stuff is all gone so hard to say but my guess is 3200 3300 don't quote me if someone knows would like to know

X2. I'll go with this.

 

[Deeznuts]

I think you need a whole lot more converter stall speed. With a off the shelf 3000-3500 rpm converter, my guess is 11.60's put a good 8 " 5000 stall converter specd to your combination in it with 4.30's and a 28 inch tall tire and it should be around 10.90's

My 71 with iron block, aluminum heads, fiberglass hood, aluminum wheels weighed with me(175 lbs.) in it 3475 lbs. and my 72 weighed 3300 lbs. with about the same setup with both cars having bench seats, 3/4 tank of gas, bumper jack/spare tire

So typically 3300-3400 lbs.

Yep you need to get a converter built for your motor for it to run like it should.
Not an off the shelf converter.

I had the converter built by my buddy that has a transmission shop I'm having him build me a 4000 as of today if the car was to be a strictly track car I would be tossing even lower gears and even higher stall. I like to drive to car shows and stuff like that. It's already probably going to tach really high with the 3.90s and a 4000 stall
Prolly going to be 50 -55 mph highway cruiser hahahahah

 

[Maintain]

Approx 12 seconds, 110 mph

 

[sbc1320]

Approx 12 seconds, 110 mph

Nope, wouldn't even break a sweat running an 11.50 at 120mph

Nothing ever runs perfect the first day out! But I agree, one could squeeze some nice times from this combo.

Mine's been ready since I timed it on the engine stand, fired it in the car and it was dead on. I never crank one till it's ready to run. Haven't made any changes to the engine/tune since I cranked it 3 years ago other than going over the solid lifters once I got it up to temp. Never moved distributor as I timed it at 26* initial on the engine stand and started it in the car and it was dead on.

I guess I should have been more clear. It may run nicely, but no combo runs it's best ET without tuning at the track. It's one of my favorite part of a project. Making run after run and whittling away at the ET.

 

[40Coupe]

Should go 10's no problem but for it to do that you absolutely will need a quality torque converter that stalls somewhere around 500 RPM over/past peak torque.

 

[wht73]

@120 it better be doing 11.0's with a <1.50 60' @ 3500/3600 lbs

 

[RifRaf]

Somewhat similar setup that I have in my '74.
Starting line traction is going to be an issue at the track... even with a 255 drag radial.
I'm guessing 11.90's @ 114mph (that's what I've run in the 1/4 with my 400sbc using 255's and thru the exhaust).

If you were to run slicks, I would guess low-mid 11's at around the same mph.
