LS Oil Fill Cap with Billet Center - 241-224 modern-day-muffler 6L V8 1977 - 1978Overview: Holley's new Oil Fill Cap for LS engines removes the oil fill tube that come stock on LS engines and replaces it with a cap that can be configured five ways plus custom option! Our cap screws directly into all stock valve covers! The base is made of the same glass filled material as the factory to ensure durability. Each cap comes with an aluminum insert that can easily be painted before assembly, and a domed Holley decal can be placed on
