Timing Chain Cover, 1967-76 Skylark/Riviera V8, 400-430-455

Precisely cast aluminum housing

A must-have for 400-430-455 engines

Now available! This timing chain cover is designed to be an excellent replacement for original equipment used on all 400-430-455 Buick V8 engines. The cast housing features machined oil passages that are slightly larger than stock as well as radiused transitions for improved flow. A crank trigger provision is incorporated into each cover and oil is kept inside the engine with a modern neoprene crankshaft seal. The oil pump location has been slightly repositioned to allow clearance for a double-roller timing chain if so desired. Sold per each, this cover is ideal for your engine build-up.
