AMC Front Timing Cover 304-401

The PROFORM AMC Front Timing Cover 304-401 is a precision-engineered replacement component designed for AMC V8 engines, specifically those displacing between 304 and 401 cubic inches. This one-piece timing cover serves as the critical protective barrier for your engine's front-end timing chain and sprocket assembly, shielding internal components from dirt, debris, and oil loss. Enthusiasts and professional mechanics rely on this cover for both OEM restorations and performance engine builds where factory-correct fitment and reliability are non-negotiable.

Constructed from lightweight aluminum, the AMC Front Timing Cover 304-401 delivers durability without adding unnecessary weight to the front of the engine. The natural finish provides a clean, stock appearance while the aluminum material resists corrosion and thermal stress inherent in high-temperature engine compartment environments. The one-piece design eliminates the sealing complexity of multi-part covers, reducing potential leak paths and simplifying both installation and future maintenance. Measuring 14.3 x 6.9 x 14.4 inches and weighing just 6.54 pounds, this cover integrates seamlessly with the AMC V8 block geometry, ensuring proper alignment with crankshaft, water pump, and accessory drive components.

Builders and restorers of classic AMC muscle cars—particularly those working with 304, 360, 390, and 401 cubic inch V8 powerplants—will find this timing cover essential for engine assembly, rebuilds, or swap applications. Whether you're returning a vintage Javelin, Rebel, or Matador to show-quality originality or constructing a period-correct street engine, proper front-end sealing is critical to preventing oil seepage and maintaining internal cleanliness. Installation requires basic hand tools and familiarity with engine gasket removal; always verify fitment against your specific engine block casting and intake manifold configuration before purchase.
