This will tell you in basic, that anything over 10W-40 in a slant is asking for trouble. Anything over stock oil pressure is too. Comp cams is a no no because they are nitride hardened. Especially if you combine one or all of those with high engine rpm.

Basically, any 10W-30 or 10W-40 engine oil will be fine and brand doesn't matter. Just add a zinc or zddp additive to protect the cam, and lots of people will even debate the neccessity of that. The additive to me, is just harmless extra protection. You can order the additive from www.summitracing.com.

Also too, don't use a fram oil filter. Wix #51515(seriously, that's the part number, that's the only reason I can remember it) is much better. They can be ordered at summit racing, o'reilly's or advance auto. Autozone doesn't carry wix and I don't know about NAPA. But the NAPA gold filter is a Wix 51515 rebranded plus $2.
