Distributor Gear .468 ID Ford - Melonized

The COMP Cams Distributor Gear .468 ID Ford Melonized (part number 431M) is a precision small-block Ford engine component engineered for OEM and performance restoration applications. This distributor gear features a 0.468-inch shaft ID and is finished in black melonized coating—a durable surface treatment that resists corrosion and wear under continuous operation. When selecting a distributor gear for small-block Ford engines, proper shaft diameter and material composition are critical to reliable ignition timing and long-term engine stability.

The melonized finish represents a proven treatment in automotive engine rebuilding and restoration work. This process creates a hardened surface layer that extends gear life and protects against friction wear that occurs in the distributor housing. The iron construction provides the rigidity required to maintain precise engagement with the camshaft, directly affecting ignition curve accuracy and engine performance consistency. Builders and restorers working on small-block Ford engines recognize that proper gear specifications ensure correct distributor advance rate and eliminating aftermarket fitment issues.

This component is essential for anyone rebuilding, restoring, or upgrading a small-block Ford engine's ignition system. Engine builders, restoration shops, and enthusiasts working on 289, 302, 351W, or compatible small-block platforms rely on OEM-specification gears to preserve original performance characteristics or match replacement distributor assemblies. Proper distributor gear selection prevents timing instability, excessive wear on the distributor shaft, and potential engagement failures that could compromise engine reliability.

COMP Cams maintains a strong reputation for distributing powertrain components that meet original specifications and aftermarket performance standards. This distributor gear fits within the established ecosystem of small-block Ford restoration parts and works as a direct replacement or upgrade option for original equipment applications.
