I was wondering what my car should run with gt40p heads, cobra intake,150 shot and 373 rear. It is an auto.

I have close to those mods 3.55 gears + a cam and -the intake, and a few other bolt-ons, any how my best is 12.006 @116

Yes that will help. Low 12s/high 11s are very possible depending on how much the car weighs.

i was hopping to get a 11.80 or 90 out of it. is it safe to hit it with a 150 on a stock bottom end.

Yes very safe.

Didn't 92s have hypereutectics...not a very large window of safety there. You'll be wanting a wet kit and I'd definitely start with about 5 degrees of timing pulled out just to make sure. You can gradually add some back in after you confirm there is no detonation. Detonation with a cast piston will result in a major engine "redecoration".

No 93s did. I am about ready to put a similar setup in mine...GT40 heads and cobra intake (both ported) B cam, other bolt ons, built AOD with 3500 stall (if i can find one)...and of course a 150 shot of nitrous for me too...I am hoping for some 12s, maybe lower

OK...didn't remember which year the switch happened
