We find using the lift at Top Dead Centre method to be the simplest and most effective. First you must establish Top Dead Centre (TDC) accurately. Once TDC is achieved, with the camshaft in place, insert a Cam Follower into the No. 1 Intake Lifter bore. Now place a pushrod onto that cam follower and mount a Dial Indicator so it is in line with the pushrod. Make sure the cam follower is on the heal (bottom) of the lobe and Zero the dial indicator. For chain driven camshafts, rotate the camshaft in the same direction of Crankshaft rotation until the lift at TDC stated on your Camshaft Data Sheet is achieved. Now you can install the chain and sprocket set. For gear driven camshafts such
