Arias Components’ Timing Cover for the Chevrolet W-Block has that vintage finned-look that stands out from the rest. Made from the original ‘60s “PARKER” casting pattern, this cover clears most timing chain and gear drive setups. Camshaft access hole allows timing changes without disassembly.  Includes oil seal.

**NOTE** Cam hole cover plate is additional.  Choose between “blank” (with fins) or with boss for pump mounting (requires drilling bolt pattern for pump indexing).
