Default Estimate me LQ9 370 !

I was wondering is someone could give me an estimation of my new build im figuring 500hp ..


TSP lq9 forged short block
Diamon -2cc flat top pistons
Stock gm crank
Ls7 lifters
7.4 hardened pushrods

Which injectors??

Patriot Stage II 2031 pre assembled heads

T56 routed back to stock 10 bolt
*Contemplating a moser 9" with 4.11s

1 3/4 " long tubes
Fast Lsx r 102 mm intake

With a thunder racing Trex cam .608/.612 with a 110 LSA

Going to be tuned by speed inc in Schaumburg, IL




What do you guys think do things look right? this is my first ls build.
The Cam I bought its the one i want i got it for a steal ($180)
The Headers I got with the car.
I am thinking pre assembled because i dont have a car as of right now. That was my only car.

1999 trans am 6 speed (t56)

I would consider stepping up to 1 7/8" headers if you plan on going over the 500hp mark.

just my .02
