that cam you recommended, with 240+ duration at .050 is way to much for his low compression, it might sound good at idle but it will serve itself useless under load. best to match cam with the heads and compression and 416 castings reform their best with a .470" lift with out mods......what you are trying to accomplish with your car, try an isky 270 mega cam......it has a 108 LSA, that will give you a nice sound and work well with your compression.
