Ford BB/351C V8 Pro Series Pro Billet Distributor

• Magnetic pickup trigger for precise timing with an external ignition box

• Pairs with a 35,000V+ coil and ignition box for high-output builds

• Direct fit for Ford 351C, 351M, 400, 429, and 460 carbureted engines

• Machined aluminum housing with steel gear for durable timing control

Upgrade your Ford 351 Cleveland, 351 Modified, 400, 429, or 460 V8 with this Pro Series Pro Billet distributor, built with a magnetic pickup trigger for use with a compatible external ignition box and coil. This setup is designed for higher-output ignition systems on Mustang, Torino, Ranchero, F-Series, Bronco, Thunderbird, Cougar, Montego, Lincoln Continental, and De Tomaso Pantera applications.

This distributor is built for the Ford 335-Series and 385-series big block family and will not fit Ford 351 Windsor (351W) engines. The housing is machined aluminum with a steel drive gear best matched to cast iron hydraulic or solid flat-tappet camshafts, and rotation is counterclockwise. Requires a compatible external ignition box and a coil rated at 35,000 volts or higher; also requires a 12-volt electrical system with an alternator and is not compatible with generator-based charging systems or vehicles still running an active ballast resistor in the ignition circuit — the resistor should be removed or bypassed as part of installation. Timing is set through mechanical advance only.

What Is a Pro Billet Distributor?
A Pro Billet distributor uses a magnetic pickup trigger but, unlike HEI or Ready-to-Run designs, requires a separate external ignition box in addition to an external coil rather than housing that control on board. This setup is common in higher-output or race-oriented ignition systems where the buyer wants to pair the distributor with a specific external box and coil combination rather than an all-in-one unit.

Performance Benefits
The magnetic pickup trigger delivers consistent, wear-free timing signal without the point drift of older breaker-point systems. Because the ignition box and coil are external and separately selected, this setup allows the ignition system to be matched to higher-output requirements than a self-contained distributor typically supports. Mechanical advance handles the timing curve across the 351C, 351M, 400, 429, and 460 family, keeping the system straightforward to set up and tune.

Do I need an external ignition box with this distributor?
Yes. This Pro Billet distributor requires a compatible external ignition box in addition to an external ignition coil. Unlike Ready-to-Run or HEI distributors, it will not operate without an ignition box.

Will this distributor fit a 351 Windsor?
No. This distributor is designed for Ford 351 Cleveland (351C), 351 Modified (351M), 400, 429, and 460 engines. It is not compatible with the 351 Windsor (351W), which uses a different engine block and distributor design.

What type of advance does this distributor use?
This distributor uses mechanical (centrifugal) advance only. Three advance bushings and four advance springs are included, allowing you to customize the advance curve for your engine combination.

Does this distributor include a coil or ignition box?
No. Neither the ignition coil nor the ignition box is included. This distributor requires an external ignition coil rated at 35,000 volts or higher and a compatible external ignition box, both sold separately.

What direction does the rotor turn on this distributor?
The rotor rotates counterclockwise, viewed from above, which is standard for Ford 351C, 351M, 400, 429, and 460 engines.

What distributor gear is included, and will it work with my camshaft?
This distributor includes a steel distributor gear, which is best suited for cast iron hydraulic or solid flat-tappet camshafts. If your engine uses a roller or other specialty camshaft, verify the recommended distributor gear material with your camshaft manufacturer before installation.
