Engineered to fit all LT1 and LT4 engines, this timing cover features a drive hole specifically for mechanical water pumps. It comes complete with new gaskets and all necessary attaching bolts for a straightforward installation. This timing cover can serve as a direct replacement for the GM 1996-1997 LT1 timing cover (GM part #12550032). When considering installation, ensure compatibility with your specific engine configuration. Associated parts, such as crankshaft position sensors and sensor plug and bolt kits, are available separately.
