The Chevrolet HEI Distributor is a favorite for muscle cars, street rods and even circle track racers. The integrated coil keeps underhood wiring clean, and for race cars, the idea of running one wire to the distributor keeps things simple. However, when it comes to performance, the stock HEI falls short. The MSD Pro-Billet HEI picks up where a stock HEI falls short with a digital module and high output coil, so there is plenty of spark energy combined with improved dwell and timing control. Ready to install in your engine! Easy-to-adjust mechanical advance ...
