Thanks Jim. I don't normally play with Chevy's so I don't know about current cams, etc. My sbc days ended back when the .30-.30 cam was the hot setup.

What is this cam, and does it simply slip in, or are better springs, etc. needed. I have a brand new set of 305 Vortec heads that I am going to use for just that reason, they are brand new. I figured if I stayed with the stock marine cam I wouldn't run into spring bind problems, etc.
