I think the cam on the '78 is milder than the one on the '76

Best to keep the cams and heads and carbs the same. They are a package.

That's right, the '76 cam is a little hotter than the '78, but I am also installing rebuilt '76 carbs which should work just fine with the "76 cylinder heads that have their original "76 camshafts. I can't see any difference in the heads themselves, just thought I'd ask in case there is.

I have 1977 carbs, heads and cams on my 1978 block and you cannot tell the difference from a 1977 with the exception of being a bit quieter block. I of course had to modify my 77 carbs to work like 1976 carbs.
