I installed the cam "straight up" I degreed the cam per Comp Cams instructions for Intake centerline. That is, to note degree wheel @ .050 before make lobe lift and .050 after. Add the two degrees and divide by 2. The result was 106.5 which is close enough to the 106 on the cam card. Then I used the "advance 4 degree" slot on the crank gear. Checked the degree again and i'm at 103 degrees. What gives? is this correct? Because I was expecting 110 degrees. Am I looking at things backward?
