That wouldn't be a bad idea! Thunder V12 builds there 702's with two "Demon" 500 cfm carbs, You may want to get a hold of them and see what they have to say

I agree. The Holley 500 should be great since the V12 is (from what I understand) just two 305s with a huge block. Air intake should be about the same. I bet it'd be a huge improvement in performance. Expensive though since they're about 250-300 bucks a piece.
