Choosing a cam is often something that seems shrouded in mystery. The manufacturers have a hundred years of technology to draw from and millions of dollars and man-hours expended on the research, development and testing of camshafts. They have used that experience to come up with thousands of lobe profiles and grinds that attempt to cover the whole broad spectrum of engines and applications. It's possible that an off-the-shelf grind might be perfectly fine, but it can't hurt for you to look into a custom designed/ground camshaft if a particular combination falls between what's readily available. Most all the cam companies will set you up with a custom ground cam for a fee. And most companies have tech lines and web sites to help you pick the right grind. Take the manufacturer's expertise and recommendations into account when deciding on a cam. | Choosing a cam is often something that seems shrouded in mystery.

| + | This is no longer true. There happens to be a mathematical equation that you can use to calculate exact values for valve seat durations, net valve lift, rate of lift and lobe centerlines. It has been around for years, and was written by Dick Jones, used by Mike Jones at Jones Cams, and written into an easy to use and inexpensive camshaft requirement software. It gives you the exact values for valve seat duration, durations @ .014, .016, .018, .020, .050, .100, .200, .300, .400, net valve lift, cam lobe lift, lift @ TDC, lobe centerlines and profile footprint. It takes 3 to 4 minutes and has been proven to be accurate over the past 30 years. There is nothing as accurate. Controlled Induction camshaft requirement software guarantees it. | ||
