Cam Degreeing How Important?
Let me start by saying I believe degreeing a cam to the cam grinders specs
will undoubtedly help to achieve maximum power from that particular cam.
But is there a lot of power lost by being off 2, 3, or 4 degrees off. I mean are you really going to feel the power difference in the seat of your pants, or is it going to take a time card to really know. Also is the power really lost or is it moved to a different rpm range. Advancing a cam increases bottom end and advancing increases the top end. It seems to me a few degrees would move the power to a different rpm range more than it would actually lose the power.
I doubt that the factory degrees the cam in every engine that comes out of the factory but yet most of the comparably equipped cars seem to run about the same. How many degrees are lost to a worn or stretched timing chain?
I'm thinking with a stock style timing chain there could be a 1/4 to a 1/2 a degree within the first 2 or 3 thousand miles. What got me going on this is I raced a lot of years and had some fast cars before I ever got into degreeing the cams until later on. It seems that some of the rhetoric about degreeing cams would almost discourage some from even attempting to build a warmed over stocker because they don't have the extra money or the knowledge to have their cams degreed. That being said, it is a good idea? Probably
Is it a absolute must? I don't think so. IMHO
