1962-2021 Chevrolet MSD Read-To-Run Circle Track-Race HEI Distributor, GM HEI w- 4 Pin Module 8365

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 MSD's 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, there's 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!Features:A complete performance HEI distributor upgrade for Chevy V8 enginesSupplied with brass terminal distributor cap and rotorFull spark energy output to 9,000 RPMSupplied with a 8.5 amp, single spark, inductive discharge ignition module, MSD PN 83647, and MSD HEI Coil, PN 8225Special oil tract improves lubrication to the distributor and cam gearNylon pads ensure smooth operation of the advance weightsAdvance weight pins are staked and tig welded to the plateMechanical advance assembly can easily be locked outAdvance plate and weights are fine blanked from chrome moly steel and QPQ coated for friction reductionPolished steel shaft is QPQ coated and guided by a sealed ball bearingCNC machined billet aluminum housing and billet aluminum baseVacuum advance canister for improved economy (can be locked out)Easy-to-adjust mechanical advance with supplied springs and stop bushingsCARB E.O.
