My zl has a 2.38 and a 10% lower now.. that is about 16-17 #s with everything, cam, headers, ported blower, the works. Do the 2.38 and don't look back

If you do end up getting a squealer ( my name for blowers that get noisy needle bearings behind the snout, just get ahold of me and ill tell you how to fix it.

what are you making power wise with your zl1 set up and are you still on the stock clutch?
