Well, the easiest thing to do would be to go to Prosystems' website and fill out and submit one of their carb build sheet forms. Patrick will get back with you very quickly, and while he's not gonna tell you part by part what your carb will consist of, he will likely tell you what main body he'd use and approximately what CFM he'd be shooting for.

My car is a stock bottom end 6.0L with L92 heads, a mild cam, Vic Jr, stepped long tubes, and a 5000 stall in a 3450 race weight car. The carb he built me is based around a 950HP main body and flows 846 CFM according to Patrick. I haven't had it to the track yet, but I'm real pleased with how the carb acts on the street.

The cam will work fine and a 750 will also do well. a larger carb will get a touch more HP but cost a bit of low end TQ that is not noticeable by the butt-o-meter.
