Cams for Dummies ??

Good ask, but probably the most controversial subject in hot rodding. So many variables that there is no such thing as the perfect camshaft. That said, there are reasonable guidelines that are widely used for the average engine builder and most of the info you'll find here is from many years of trial and error from some great people. Even the pro grinders will disagree on one specific combo. That's why the ''big boys'' of racing spend countless hours on the dyno with different profiles and head flows.
