The performance and benefits of a GM HEI are all included in a sleek black package.
GM HEI distributors that use a 4-pin ignition module are replaced by this unit.
A favorite for muscle cars, street rods, and even circle track racers is the Chevrolet HEI Distributor.
Keeping underhood wiring clean is achieved with the integrated coil, and for race cars, running one wire to the distributor simplifies things.
However, the stock HEI falls short when it comes to performance.
A strong, accurate, and high-performance HEI is answered by MSD with our Pro-Billet HEI.
Our Digital HEI Module and Coil supply plenty of spark energy combined with improved dwell and timing control.
MSD's adjustable centrifugal advance assembly is tig welded on top of the distributor shaft.
The supplied advance curve kit includes springs and stop bushings, allowing you to dial in different timing curves to match your driving needs.
For those concerned with economy, a vacuum advance is included.
All of this is assembled around a great looking and precision CNC machined housing that is black anodized for great looks.
Our cap, rotor, coil cover, and heavy-duty gear are supplied with the distributor, making it ready to install in your engine!
