Overview:
Holley now offers a solution to the plastic OEM timing chain covers on 1996-up Vortec Small Block Chevy engines. Our cast aluminum timing chain covers are an excellent upgrade from the OEM part, offering the superior durability of an aluminum part with improved functionality.
These cast aluminum covers feature timing indicators molded into the body and are available with or without a crank sensor provision to accommodate both carbureted and EFI applications. The covers are available in two finishes; Natural Cast and Satin Black. They are packaged with a high quality gasket and E-coated mounting hardware for added corrosion resistance
