i didnt know where to ask this so i asked it here, haha, what is the big difference in the 2002 Z06 and why is it faster than the others? is it the gearing in the transmission or they have more power? and what is the RWHP on the Z06 01, 02 and 03? sorry i posted here!

Rwhp on the 02-03 is around 355 I believe. As far as the extra HP, I dont know for sure, but it could be a different cam.

The 01' Z06 has 385 from the factory while the 02'-03' have 405. In 02' they changed the cam, removed the pre-(pup)cats, and modified the air-box and made it more free-flowing. They also removed the maf screens on the 02-03'. As far as a performance standpoint there pretty close in performance. Hope this helps.

The '02s and the '03s are the exact same (powertrain wise).

Besides what is already listed they LS6 got hollow valves filled with sodium for reduced weight. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
