Default How powerful??

How quick of a car would these make my 97gt?

Stage 3 foxlake heads
Stage 3 comp cams
78mm throttle body and plenum
Underdrive pulleys
K&N CAI
BBK long tubes
Prochamber
Flowmasters 40s
Limited slip differential
3.73 gears
Centerforce dual friction clutch
Dyno tube

How quick would these make my car horsepower wise?

Thanks,
Mike

You better ad a stall converter somewhere around 3500 to that list if you want it to work (unless you are using a manual). Ditch the 373's and go 4 10's. But I think they other guys are right 300-325 to the wheels depending on the on tune.

im surprised nobody has said this yet... that 78mm tb is OVERKILL in the highest form. its like adding a 90mm maf to a bolt on GT. go with a 70 or 75.

I don't think stage 3's will be enough. You should get stage 5 heads/cams.

well also remember that with stage 3 cams that you are going to have to have the engine bored out a little bit for the valve clearance and also notches in the pistons for the same reason. and dont forget fuel system upgrades too. and got with a 75mm throttle body and plenum. and you may want to have a pi intake manifold port matched and thrown on there as well. and i would take a guess and say that you are going to make over 315. a lot of other people on this forum have stage 2 heads and cams and are around 300-315. and with your compression being a 97, you are going to be a little bit ahead of the rest. so id say between 315-335rwhp depending on the tune. and definatly go 4.10's...not 3.73's.
