Help with sb combo

As "tubtar" said, talking with some different cam companies can give you a lot of info. I'm thinking the Victor340 intake and a cam somewhere in this range will get you started.......

I'm staying a little conservative with the "J" heads and unknown flow numbers. I like the single plane for the fact that with the 750 carb will still have decent mixture velocity.

Until you get some passes under your belt, it's a little hard to narrow down on a exact combination. I would think your gonna be using slicks around 28" tall at the track?
