head ? before I put it back on the road
This is my setup:
02 stock ls6 shortbock (25K miles)
alum. 317 heads w/ 918s (ALL NEW and unported)
Vic jr w/ elbow
4k stall
T61 turbo
This is a truck manifold setup, 7.5 psi max; more street than strip right now. I'm upping the turbo to a T76mps. Should I go ahead and get some AFR's, been looking at the 205 76cc and the 225 72cc or should I just stick with the 317's? In the next yr. I'll be getting a forged 370-383.
