As far as cfm recommendations go, im no expert
as far as the carb goes though, I am running the exact same carb as skep and have to say i love it! bolt it on, set the idle, and go. The jetting was almost spot on, i lowered the primaries two sizes i believe, and i needed to up the squirters to a 35 front and back...other than that its working great
i dont think ill ever go to anything other than a box stock holley again...brand new carb you can tune yourself and not have to worry about other peoples work
