Do you have any specific needs for the cam? wanting something just for a spirited driver chances are you would be happy with about any smallish performance cam available. Your engine combo is kinda mis-matched, heads are way overkill for a performer intake and 600 cfm carb, and your compression is kind of low for many performance camshafts.. with that said you might want to look for a cam intended for EFI, as they tend to limit overlap and that will not bleed off the little compression you have. But like i said if you are not goal oriented then read through some cam descriptions and pick a few that fit your rpm range and user application.. ie a street / strip cam.
