How to Pick Your own CamShaft better.

I've watched this guy's videos before.... He has a shop and is knowledgeable but GET TO THE POINT! Keep it pithy..

One thing he does well is explaining ICL/ECL. LSA is a result of the math. So when you design a cam those figures determine the LSA.... They don't figure LSA first.... And two different sets of ICL and ECL will change the performance of the cam even if the LSA is the same. A 104/108 will act differently than a 102/110 even though the LSA is the same. Important in a performance cam.
