Features:

- Wires Are Pre-Cut To Exact Specifications
- Bolt-on Performance
- The MSD 8.5mm Super Conductor is the ultimate performance wire! Its extremely low-resistance combined with the ability to suppress Electro Magnetic Interference is a combination that defies the common laws of physics. Less resistance means more energy is going to make it to the spark plug to ignite the air/fuel mixture. The Super Conductor uses a copper alloy conductor resulting in less than 50 ohms per foot of wire! This ensures that the most energy possible makes it to the spark plug. By helically winding the conductor around a special core, we are able to produce a highly effective choke to keep the EMI inside the wire and away from other electronics. This combination is encased in a heavy duty sleeve that will withstand abrasion and high temperatures. Cap off each end with our Dual Crimp Terminals and you have the best wire available.

- 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.MSD answers the need for a strong, accurate and high performance HEI with our Pro-Billet HEI. The distributor is supplied with our Digital HEI Module and Coil so there is plenty of spark energy combined with improved dwell and timing control. Tig welded on top of the distributor shaft is MSDs adjustable centrifugal advance assembly. Three sets of springs and four stop bushings let you dial in up to 24 different timing curves to match your driving needs. Plus, theres a vacuum advance for those concerned with economy. All of this is assembled around a precision and great looking CNC machined housing. The distributor is supplied with our new cap, rotor and coil cover and heavy duty gear so it is ready to install in your engine! Note: The PN 8365 is designed to replace GM HEI Distributors that use a 4-pin ignition module.

This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pick-up mounted in the housing. This high output magnetic pick-up is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick-up is maintenance free! Just above the pick-up is MSDs adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application. Must be used with an MSD 6, 7 or 8-series ignition.
