Our EFI 24x™ SBC conversion with 1x camshaft position signal within timing cover is the best solution for equipping your SBC engine with the 24x crankshaft and 1x camshaft signals of a Gen III LS-Series engine. Requires a step nose camshaft (like 1987-newer hydraulic roller engines). Includes billet aluminum timing cover, Cloyes True Billet double roller timing set (based on Cloyes 9-3545X9 True Billet double row timing set), 24x crankshaft reluctor, CMP sensor, and CKP sensor. SBC balancers wider than 1.325" will not clear timing cover and CKP sensor.
