Degree New Comp Cams Cam

rklein383 said
I have installed my new Comp Cams High Energy camshaft. The instructions state that Comp Cams grinds most of these cams 4 degrees advanced.

I check my cam centerline. It is 102 degrees. The cam card says the cam centerline is 106 degrees. Since this is 4 degrees advanced, is this right? Or should it be right at 106?

I have run out of time tonight. Tomorrow I plan on verifying that I have TDC exactly right and basically repeat the whole procedure.

You need to back it up 4* to put it where comp wants it.

FWIW, when these cam guys talk about 4* advance ground into the cam, all that means is instead of needing offset keys or bushings, when you install the cam "dot to dot" it SHOULD be 4* ahead of LSA. In reality, tolerance stack up usually means it won't come out correct. So "4* advance" ground into a cam is just not a performance thing. It just hopefully makes it somewhat easier to degree in.
