Why do some cam companys advertise the lobe center and some lobe seperation? Why not both. I know there is a difference between the two terms just a little confused as to why the cam companys arent on the same page. If you install a cam straight up with no advance are these numbers the same?

Lobe centers(center line)are the midpoint of the lift curve to check the cam during installation,the lobe seperation angle is the distance in degrees between the intake and the exhaust centerline.most people use lobe center as a slang for lobe seperation.They cannot be the same,you can change the lobe center location with bushings or a timing gear but lobe seperation cannot be changed without moving the lobes on the cam...hope i didn't sound too complicated

Thanks Rico, I understand the difference, just wondering why some cam companys list the seperation on there cam cards (like comp) and others just the centerline. Why not both?
