I have a question about cams most gear heads understand lift and duration but what about for example a 900 base circle 108 lobe center what does it all mean to me choosing a cam to fit my application? I have never really understood this I always count on the cam manufacturer I don't know how generic the info they give is don't get me wrong I under stand some just all info together how does it effect each other
