Upgrading or rebuilding a 1996 and newer Vortec Small Block Chevy calls for components that match your performance goals while improving long-term durability. The original plastic timing covers used on many of these engines can degrade or crack over time, particularly in higher performance or crate engine applications. The Holley Cast Aluminum Timing Chain Cover offers a stronger, more refined alternative designed to enhance both reliability and appearance.
This cast aluminum cover serves as a direct replacement for the factory plastic units found on 1996 and newer Vortec Small Block Chevy engines, superseding GM part numbers 10244600, 12523972, 12523973, 12558343, 12562818, and 93800970. It is also well suited for Chevrolet Performance crate engines originally equipped with a plastic cover. Versions are available for EFI configurations with crank sensor provisions, as well as carbureted combinations that do not require the sensor opening. Integrated timing marks are cast into the housing for easy reference, and the cover is designed for use with 8 inch Vortec balancers along with many popular 8 inch aftermarket options. Compatibility extends to both factory style and aftermarket water pumps. Finish options include Natural Cast and Satin Black to match your build’s style.
Built for long service life, the cover incorporates an over molded FKM front seal to help prevent seal movement under elevated temperatures, a common issue with some aluminum designs. Installation is simplified with the included premium gasket, corrosion resistant E coated fasteners, and dowel pins to promote accurate alignment and a secure fit. Backed by a 1-Year Limited Warranty.
