600rwhp & Boost to get it~
Post engine, trans, stall, turbo and other mods. Of course post what psi as well.
I am gonna be running a 5.3 with cleaned up 862 heads, upgraded valve train, tick performance stage 2 turbo cam, on3 76mm. Through a th400 and 9.5" lock up stall
Curious what psi will get me to 600rwhp hoping around 12. I would like to stay around 12psi for a street car for peace of mind till i build a forged bottom end.
