Holley’s cast-aluminum timing chain covers are a terrific upgrade to their plastic OEM counterparts on 1996+ Vortec small-block Chevy engines, offering superior durability and improved functionality.
With timing indicators molded into the body, and available with or without a crank sensor provision, these covers accommodate both carbureted and EFI applications. They are available in two finishes—Natural Cast and Satin Black—and are packaged with a quality gasket and e-coated mounting hardware for added corrosion resistance.
