Then, a camshaft lift indicator was placed inside the intake lifter hole. Brulé referred to the COMP Cams spec sheet for the cam’s intake centerline. COMP Cams recommended 106 degrees at intake centerline. Brulé then turned the crankshaft clockwise until the camshaft indicator read 0.020 and recorded that number on the crankshaft wheel: 74.5 degrees. Then, he continued to turn the crankshaft clockwise until he got 0.020 on the camshaft dial indicator and recorded that number: 136 degrees. Add both numbers (75 + 136 = 211) and divide the total by two (211 ÷ 2 = 105.5). This number is where the cam is set in degrees (105.5) and should be as close to the recommended intake centerline per your cam spec. If your cam is off then it is necessary to adjust the cam gear and start all over, including measuring the piston TDC.
