Re: Duntov 30-30 302 Camshaft
GM designers back in the day were able to use "grocery getter" valve springs and basic parts (except hardened rockers) to make a great running engine. I am never quite sure why people think that changing the 30-30 cam for something else is such a great idea. Be sure to read the CRG article on lashing a 30-30 cam if you go that way. The Comp 1.52 roller tip rockers are a real good upgrade idea.
If you go with another cam you probably need to look at the proper springs and parts to compliment that cam. What does a "more modern profile" do for you? Does it last longer, have less maintenance? Changing the power charecteristcs I understand if you want more low end torque.
