MSD 84791 Ford Street Pro-Billet Distributor with Steel Gear - 289/302

The MSD 84791 Street Pro-Billet Distributor is engineered for high-performance Ford 289 and 302 small-block engines that see regular street use. Built around a CNC-machined 6061-T6 billet aluminum housing and billet aluminum base, this distributor delivers race-proven accuracy and long-term durability. The compact housing is 5/8" smaller in diameter than stock Ford distributors, freeing up valuable clearance in tight engine compartments.

The included steel distributor gear is compatible with hydraulic roller camshafts, making this an ideal upgrade for engines running modern valvetrain configurations. A maintenance-free magnetic pickup and precision reluctor deliver stable, accurate trigger signals throughout the entire RPM range, while the polished steel shaft is QPQ coated and runs on a sealed ball bearing for high-RPM stability and endurance.
