Great, thanks for the good advice. Hows the idle on the .520/.540? Lumpy?

Lumpy means different things to different people. What are you looking at for parameters??

If this was his cam it will still be lumpy even with the 4" If this is the cam: http://www.summitracing.com/parts/cca-20-231-4/overview/

It will be less than "very lumpy", but still lumpy.

That cam has 66 degrees of overlap.
