My friends 02 WS6 with a Comp Cam and ported stock "LS1" heads did 455/435 wheels. (also has headers, exhaust, and K&N kit)

He's run a very traction limited low 11's on just the motor. If he had found any traction he definitely would have been kicked out.



Actually he's a little of above where he should be. 437rwhp is pretty high for a cam-only Z06. I've seen H/C cars that don't do better than that. The heads on that LS1 must have flowed pretty well.



I agree....The only other cam-only cams that can dyno that high are the T-rex, the G5X4, and the TTP Equalizer...

Once you remove the heads for porting be it LS1 or LS6, usually the valves are replaced, and the heads are milled for compression which nets some serious power gains on these cars...

My optimal setup on this car is/was AFR 205 heads milled for 11.25:1 comp, my current cam and an Fast manifold/90mmtb setup. This combo should net me in the 475+whp range and around 445+wtq.....
