What should this car run?

[skiwesser]

Only have the stock tach, I "try" to leave at 5000 and shift at 5400RPM's

You should be in the 8.20's at a minimum. Put on some slicks, dump the clutch at about 5 grand, bang the gears at about 6 grand and it shouldnt be a problem.

[USMC302]

8.60's @ 80mph in the 8th is around 13.40's @ 100 in the 1/4 right? With a 331, even low compression, heads, cam, intake, and gears, that car should be running high 12's at the worst. Somethings wrong IMO. Your right, you should be faster.

You can get more out of that combo, My tired 302 is around 290 at the wheels, well at least thats what the online dyno says.


keep posted, and like mentioned above, dump the clutch 5k with no remorse
At 5k dump, I pull 1.70's 60's on 26x8.5 m/t's.

I think 8.20's as well, the old bolt on motor with shaved E7's went 8.75 @ 79.8 at another track.
I believe the combo of spinning off the line due to first time on ET streets, and I only had one pass that I felt good about all the shifts(but I spun bad and ruined that pass), resulted in the disappointing ET's and 60 ft's, plus I don't really like that track.

Anyway I'll get it done , should I stay on the MT's or go back to the Mccreary's?????
If I stay on the ET Streets what air pressure should I be at 16-17 lbs is my usual at that pressure the MT's spun but the taller Mccreary's HOOK, But I got the shorter MT's because I figured a 26" tall tire would work better than the 27" MCreary's which are actually dirt track tires but i've used them awhile cause they're $100 a piece and last a long time.

I run 10-12 PSI in ET streets. I do a good second gear burnout. I then dump the clutch @5000rpms and I get a loud chirp on the launch and on the shifts.

Your mph in the 1/8th is what is most troubling. You are not gonna get a much better ET with a 80mph trap speed.

What was your uncorrected HP when you went to the dyno?

[skiwesser]

I don't know?
uncorrected HP wasn't brought up, to be honest I don't know what it means??
Trap speed is what worries me too as it stayed in the 80.3-80.8 range every run.
