i'm guessing that the following bolt ons will get me close to 400 hp from my 02z28. am i in the ballpark?

stock ls1 short block
ls6 heads
hpe s cam
p & p throtle body
double roller chain
ported oil pump
long ceramic headers
off road y
lid
quality plugs and wires
and a professional tune

what do you think?

 

post up the specs on the cam, and your head gasket thickness or scr/dcr and someone will guess close...

 

yes should hit 400, but do need more info. All depends really on the cam

 

the hpe s cam specs are 238/240, 112 lsa, .605/.609 with the dual patriot springs and trick flow pushrods also running underdrive pulley.

 

400 + some.
I'll guess 415/390
