Remember its only for a maximum of 5 extra minutes. Once your RPM range is known, you will have an easy time finding some cams that may work, but how to narrow it down from there? With a good tune and free-flowing exhaust, Shelbys can pick up a bunch of power at the rear wheels with these cams. I intend to offer insight which will help in choosing a camshaft for yourself. Overlap promotes cylinder scavenging at high RPM's which is crucial to power production in a naturally aspirated engine. Most cam manufacturers give you a rough idea on track size, and a set in stone RPM range to go from, so the basic homework is done by them. If a cam has a 108 degree lobe centerline it means that the max lift on the Intake and exhaust is 108 degrees apart on the cam. Ever wonder why hotrods sound like they do at idle? After 5 minutes push them to tip more tokens to keep the show going. Lift is increased by approximately 1.14 and 1.36 mm on the intake and exhaust sides respectively. Stand on the gas pedal at 2500 RPM, and the phaser advances the intake cam to provide maximum power. By Rob Hosking – Choosing a camshaft is pretty simple.
