Another related question... It is always recomended to check the installation of the cam for the proper centerline as called for by the manufacturer. Most all write-ups or videos that show the process end up with the CL coming out correct. Mine didn't. My installation calculated out to 105 instead of 108 like the card said it should. Why would this happen? What factors could contribute to the cam not being as the manufacturer says it should be out of the box? And yes, there were 2 of us there during the degreeing process and we did it over and over and came up with the same 105 every time.
