Carburetor advice needed
 

Having some problems picking a carb to buy. I was wondering what peoples thoughts were on it. I have a 350 in a 77 Monte Carlo (big A-Body) with a stock TH350 trans, stock gearing, Edelbrock Performer heads, Edelbrock dual plane intake, cam with a duration at 292 intake/302 exhaust, and a dual exhaust with an h-pipe (that was a trick). No idea what the VE is. I know the quadrajet that was stock was a 750, but I don't want to flood it out. Any ideas?
