Re: Correct me if I'm wrong ............
Marlin,
LCA (Lobe Centerline Angle) is a term that tells you how advanced your cam is. If you have a cam that has 114 degree LSA (Lobe Seperation Angle)and you put the LCA at 106 degrees you've advanced you're cam 8 degrees. This would generate good static compression at low RPM but hurt high RPM cylinder fill. It will close the intake valve approximately 8 degrees sooner. What you get on the bottem end you give up on the top end. Alot of how the cam should be put in depends on your car set up. ex. 4 speed or automatic, 4.10 gears or 3.55, high compression motor or low low compression motor.
