2000 z28
m6
3.73 gears
APS 8lbs
ls6 intake
42lbs injectors
twin 255
317 heads (stock)
ZO6 cam
dual springs
underdrive pulley
SLP MAF
and a good tune im thinking between 500-550rwhp i hope right hahaha

Mine made 481 on a stock motor with some shitty parts and a little boost leakage........so you should be good for the 550-600 range.
