Hi Brent,
Didn't want to make an essay out of this. I was inferring that people that don't know the basic duration measurement won't be able to pick a proper cam, including me. Race cams trying to work on the street are not going to work without major input from an experienced engine builder and alot of maintenance. The tech line at comp cams does thousands of these combo's for the street and track and probably has the biggest database anywhere on what is going to work. They recommended the cam I have in my 460 now, it's a milder grind than I thought I should have but it is way quicker than it should be for a smogger. And that's basically the point,an individual has no chance of picking the right combo for his engine, it would be like picking the lottery #s.
