Holley Cast Aluminum Timing Covers 21-152

Holley cast aluminum timing covers offer a durable upgrade to the plastic OEM timing chain covers on 1996-up Vortec small block Chevy engines. These aluminum covers feature timing indicators molded into the body and are available with a natural cast or satin black finish. A quality gasket and E-coated mounting hardware for added corrosion resistance are included.

Holley cast aluminum timing cover features include:

* Available for EFI (with crank sensor provisions) and carbureted applications (without crank sensor provision)
* Includes over-molded FKM oil seal, virtually eliminating concerns of the seal spinning out at high temperatures, which is common with other aluminum timing covers
* Accommodates both stock and aftermarket water pumps
