MSD 8377 Ford 351C-460 Crank Trigger Distributor with Bronze Gear

The MSD 8377 is a dedicated crank trigger distributor built exclusively for racing applications on Ford 351C through 460 big-block engines. Engineered to work in tandem with an MSD Crank Trigger system and MSD Ignition Control, this distributor strips away all street-going hardware and replaces it with a precision race-focused design that delivers consistent, high-RPM ignition timing with zero mechanical drift.

The standard-height Ford distributor housing maintains compatibility with cast intake manifolds, while the low-profile cap assembly provides critical clearance for crowded engine bays and performance intake setups. Because the only component beneath the cap is a rotor, the overall height is dramatically reduced compared to conventional distributors — eliminating interference issues common in high-horsepower builds.

Key Features:

• Crank Trigger Design: No advance assembly or magnetic pickup — timing is handled entirely by the MSD Crank Trigger system for maximum accuracy
• QPQ-Coated Polished Steel Shaft: Specialty surface treatment reduces friction and extends service life under continuous high-RPM conditions
• Sealed Ball Bearing Support: A press-fit sealed ball bearing guides the shaft for long-term durability and rock-solid stability at elevated RPM
• Bronze Distributor Gear Included: Supplied with a bronze gear specifically suited for roller camshaft applications common in racing engines
• Low-Profile Rynite-Molded Cap: Ford-style HEI cap and wire retainer provide excellent spark containment and resist the high cylinder pressures associated with forced-induction and high-compression race engines
• Standard-Height Housing: Compatible with cast intake manifolds for flexible build configurations
• Racing Use Only: Not legal for use on emissions-controlled or street-driven vehicles

Requirements: Must be used with a compatible MSD Crank Trigger and MSD Ignition Control (6, 7, or 8 Series). The MSD Billet Hold-Down Clamp (PN 8010MSD) is recommended for a secure installation.
