The guy I know is only offering me the .484 cam. He doesn't have the .474. So I'll probably end up going with comp cams nostalgia version. Whichever one I can get a better deal on. I'm not too keen on re-using someone else cam, just my preference on that.

Are the factory springs in a 383HP not able to put up with that small of a cam lift?
