 +Thanks to Maxeffort of the XLForum for the following Flywheel Degree Charts of these various cams.((Maxeffort at this post: http://​xlforum.net/​forums/​showthread.php?​t=2074322)) 
 + 
 +The measurements are based on the .053 lift specs. Also, take note that the predominance of the intake valve opening occurs on one rotation of the flywheel and the predominance of the exhaust valve opening occurs on the next rotation of the flywheel. It takes two full rotations (720°) of the flywheel to complete the four-cycle process. (This view of the flywheel would be from the right side of the engine.)
