BBF 351-460 Crank Trigger Distributor

The BBF 351-460 Crank Trigger Distributor by MSD Ignition is designed specifically for Big Block Ford engines, including the 351W, 400, 429, and 460 cubic-inch variants. This product is ideal for classic muscle cars, hot rods, and performance trucks that require precise ignition timing control. It addresses common timing issues associated with mechanical distributors, particularly at high RPM.

The crank trigger design of this distributor eliminates mechanical wear, vacuum advance drift, and centrifugal advance lag, ensuring consistent ignition events throughout the power band. By picking up engine speed data directly from the crankshaft reluctor ring, it bypasses the distributor shaft entirely, which enhances timing stability under various conditions such as boost and heavy loads. This architecture is crucial for applications involving forced induction, nitrous oxide, or aggressive cam profiles.

Engine builders, bracket racers, and street performance enthusiasts will find this distributor particularly beneficial due to its reliability and precision. The compact dimensions of 6.9 x 6.8 x 17.7 inches and a weight of 4.45 pounds facilitate easy installation in tight engine bays without extensive modifications. It is designed to work seamlessly with MSD Ignition control modules, which are sold separately.
