RIght now Im a full bolt on HC e85 M6 C5 making around 450 whp

Im doing a p1sc A and A install this weekend and wondering what pulley to start with. Im wanting to keep the block running for one more season before going forged. Currently I have 120k on the short block.

Im wondering what you guys estimate the boost at with a:

4.25
4.0

( the 2 pulleys I currently have)

with my A&A kit on my stock LS6 I would see 5-6 ish with the 4.25". I am not sure how much different it would act on yours with the heads and cam package..

If you got both not much diffs at all go with the 4.0 if it blows time for a new motor. If you have a good tuner and he knows what he is doing here you will be good... Man good luck and have some fun with her... Robert
