Just wondering how much power my set-up should make
94 camaro z28 m6 - fully forged 355 shortblock - stock lt1 heads, lt4 hotcam, meth injection, full bolt ons, t67 turbo upgrade - plan on running 15psi of boost. I made 400/408@7psi with the stock lt1 engine lt4 hotcam - just wondering if I could reach 600rwhp with stock unported heads - Mike

 

If you get some headwork and intake match, your #'s will jump real nice!! I made 438 RWHP with mods below on stock block some headwork/intake, and I was running out of fuel. That was only shifting at 5,200!!! Once we get new injectors and settle the fuel issue we will be able to shift at 6,400 hopefully hity the 500 mark!!

 

Why not. 275+(25X15) = 650 crank horsepower.

 

I'm not sure if that'll be enough turbo for 600rwhp
