370 -385 rwhp. you'll need after market heads to get you in the 400+ rwhp. or have your stock heads ported.

Wow, I was hoping for 325rwhp. My initial caluculations are below.

330 FWHP (tuned for high octaine)
10 Intake
5-7 LS6 manifolds
50-55 Cam
5 Power steering delete
0 ported TB (not enough power to make a difference)
10-25 Exhaust dump

410ish (crank)

Assuming 15% DLL

348 Whp. (or roughly the same as a stock LS6 that has bigger cubes but a smaller cam) I thought I would be hard pressed to reach Z06 power with the smaller cubed aluminum 5.3.

Am I targeting too low?

There must me some 5.3 guys in here, or pros that know their stuff,

I'm I shooting high or low in my perdiction?

BTW, thx Pose and Cowboy
