"I'm comparing like modifications done to similarly powered cars. Granted these cars didn't have Porsche's R&D..."

I was referring to the "similarly powered" cars. Sorry for the dangling modifier... I'm a mechanical engineer, not a linguist Apologies.

Geo... what cam's have the best results in your experience? I haven't looked that far into NA mods as to research cams. How much would a decent cam run me? $400? $500?

Well, I haven't done any research into cams because they are not legal for me. However, I would certainly give Jon Milledge a call. His stuff is all the result of good R&D and dyno testing.

His cams are $640. But look at the gains. Best you will find for an NA. If I eventually go E Production racing (in the back of my mind) I will certainly go with a JME cam.
