Is you motor stock or rebuilt. cause i have had that exact cam and I built a 383 pushing 425 hp with a 650 carb. but if you motor is stock get a 600 it will work fine. 750 is to much for stock motor unless motor been rebuilt. Hit me up with any other ?'s

vehicle weight, compression, and what you're going to be doing with it is needed to answer this question...

but yes, a 650 should be adequate assuming it's mostly stock with just that cam swap...
