Thanks for all of the great info guys. I think I am going to go with the Xtreme 262 based on rpm range, compression ratio, and current exhaust.

I've got an Edlebrock RPM Air Gap intake that I'm going to use and I am seeing a lot of mixed info on 600 vs 750 cfm. I didn't realize that I could loose a bit on the lower end if I go with a 750 cfm. The tech at Holley said there is a simple formula and that even at 6000 rpm a mid 350 won't pull a full 600 cfm. Any other thoughts?

Bit more efficiency with the Aa imp and the place divertor and Jacuzzi intake will help.pop it on plane too .if that's a stainless impeller don't let anyone cut on it ,it looks like a later style unit .
