Compare the centerline to the value listed on the Cam Card. ii) Loosen the cam gear bolts on the AEM cam gear and rotate the hub clockwise and counter clockwise.Follow this link for the process to Degree the Camshaft.This should be done when building an engine or replacing a camshaft.This is known as "degreeing the camshaft.".Find the lobe centerline in relation to the piston's position in the cylinder.This changes the Timing of the valve opening and closing events, in relation to the position of the piston in the cylinder. These single-row chains are precision-machined and available in. Summit Racing Pro LS Billet adjustable timing sets and gears provide maximum strength and reliability for your engine build. Maximum Advance/Retard at Crankshaft: 4 degree. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.
