Engineered to GM standards for reliable installation, this stamped steel cover is supplied with a GM production oil seal installed, and it is a direct replacement for all late model small-block and V6/90 front covers that use a bolt-on timing pointer. It provides an award-winning total look when used with matching air cleaner, and valve covers.
