Default 2002 Z06 mods advice

Just looking for opinions of mods for my '02 Z06. Right now i've got long tube headers and CAI installed. It has not been tuned yet but runs very well on the street and at the dragstrip.

I've got a G5X3 cam to install but not sure i want to get into the engine at all! I've also got a FAST 90/90 set up to install,an underdrive pulley and 160 T.stat.

Can anyone tell me if they've done a FAST 90/90, u/d pulley,160 T.stat install on a stock motor with headers then had it tuned, what kind of power would it make?

Also, has anyone done a 4.10 gear and what kind of difference does it make at the dragstrip with a stock motor?
and with a stock motor with the FAST 90/90,pulley,t.stat and tune?

Thanks.

dont forget alot of people have clutch problems with the sotck z06 clutch when they add much more than +/- 50hp.


just be ready to upgrade the clutch (i.e. save some $$$ for it).

Just with what you have done so far plus a tune,you should be around 400 rwhp.That is a pretty quick car and going into the motor with a cam there might be paybacks.

Outlawten: If ur G5x3 cam is 114 LSA and its new and if u think its too big for ya than u can trade with mine bought from 21stcenurymusclecars.com, 228/232 .585/.595 lift and 113 LSA. Mine is bought new 2 months ago and still new, we can swap. But all in my honesty, u should install that cam and sell fAST 90, stay with LS6 intake.

Sell FAST 90 and buy 3.90 gears that goes great with G5x3 cam.
