The Chevrolet HEI Distributor remains a popular choice for muscle cars, street rods, and circle track racers, offering a clean underhood appearance with integrated coil functionality. However, the stock HEI lacks the performance capabilities that enthusiasts often seek.
Addressing this need, MSD introduces the Pro-Billet HEI, providing a robust, accurate, and high-performance solution. The distributor comes equipped with the Digital HEI Module and Coil from MSD, ensuring ample spark energy and enhanced dwell and timing control. The adjustable centrifugal advance assembly, securely TIG-welded to the distributor shaft, offers flexibility with three sets of springs and four stop bushings, allowing for the customization of up to 24 different timing curves to suit various driving requirements. Additionally, a vacuum advance is included for those prioritizing fuel economy.
Crafted around a meticulously CNC-machined housing, this distributor is bundled with a new cap, rotor, coil cover, and heavy-duty gear, ready for seamless installation in your engine.
Note: The PN 8365 is designed as a replacement for GM HEI Distributors utilizing a 4-pin ignition module.
