If you go 1:1 on a 350 it would produce 15.3 #'s of boost. On a 350 with only 8.5:1 static cr - with 14#'s of boost, that's going to raise your effective cr to 16.6:1. 15+ #'s of boost with a roots type blower is a lot for the street, can your motor hold that?

I have an 8-71 on a 383 with two BG 750 BC's on the street, it's very streetable, if not a little brutal. I opened up all eight primary idle air bleeds to help idle quality, and jetted it down two numbers on both sides, other than that, nothing.
I'm the one your momma never told you about...
