Compatibility and Fitment
Small Block Chev 2-Piece Billet Timing Cover Kit suits most Gen I SBC blocks with conventional front seal and standard bolt pattern. Clearance with double-roller chains and cam buttons is typical; check water pump, fuel pump eccentric and pointer alignment during mock-up. Use the supplied or equivalent front seal and confirm balancer hub diameter before final assembly.
Compliance and Safety
Install to a clean, burr-free block face. Use manufacturer torque values, apply suitable sealant at pan corners, and verify pointer TDC after balancer fitment. After initial run-in, inspect for oil weep and re-torque fasteners as required. Dispose of oily rags responsibly and follow workshop safety practices.
Marine Applications
Ideal for inboard ski-boat and marine SBC builds where frequent cam timing checks are required. The rigid billet design helps maintain gasket crush under vibration, while the split cover reduces service time with the engine in-hull.
