So I have my procharged 383 out of the car and I am freshening it up. I am thinking about swapping cams. The cam I have is a billet custom grind. It made good power but I think there is more in this build and I think the cam is holding me back. I had Llyod Elliot spec a cam out for me. Im debating on swapping it. What do you guys think? Will this cam make more power over what I have with 20 lb boost?
Present cam. 233/241 .545/.550 115+4 LSA
LE: 226/239 .565/.587 112 LSA

I'm in the more overlap is better camp, especially with forced induction, so the LE cam appears to be directionally correct. I'd be tempted to tighten the LSA a bit also.

In every test that I've read on the subject, engines equipped with centrifugal superchargers make more power with more overlap (assuming that the intake pressure is greater than the exhaust pressure). I've posted some links on this topic in the past, just need to do a little digging to find them.
