Hey guys, just finishing up a build on my 02 Z06. hoping to get it tuned in in the next few weeks The car before had a GT11 Cam, 1 3/4" LG Headers, ported heads, 3.73 gear and a Fast 90/LS2 Throttle Body, Stock Ti mufflers, FMS 42lb injectors and put down 425hp at the wheels. I upgraded to Trickflow Fast as Cast 220 heads with Brian Tooley springs, Ported Mamo Fast 92 Intake, American Racing 1 7/8" headers, I.D.1000's injectors, and 3" off road X-pipe. Hoping to be in the 460-480 range on pump gas. Down the road I want to run E-85 after I upgrade my fuel pump. What kind of numbers should I expect? I have seen similar setups make near the 500hp mark.

Sounds like you had a pretty nice set-up to begin with. I hope you got a good price for the take-off parts. With the replacement mods you installed, you might see 460-480, but that depends on the dyno. The only way to really tell would be B4 and after comparisons on the same dyno.

It will be tuned on the same dyno.

I'd expect 460. Selling any of the old stuff for a low price?
