The Chevrolet HEI distributor is a favorite for muscle cars, street rods and even circle track racers. The integrated coil keeps under mount 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.

Product Features:

• Complete performance HEI distributor upgrade for Chevy V8 engines
• Supplied w/Brass Terminal Distributor Cap And Rotor
• Full Spark Energy Output To 9000 Rpm
• An 8.5 amp; single spark; inductive discharge ignition module
• Includes MSD PN[83647] and MSD HEI Coil PN[8225]
• Special oil tract improves lubrication to the dist./cam gear
• Nylon pads ensure smooth operation of the advance weights
• Advance weight pins are staked and tig welded to the plate

Leave it to MSD to build an all-out performance distributor to replace the OEM GM LT1 Optispark. We machine an entire billet block of aluminum down into a precise housing that fits in place of the factory piece. Then, we fill it with a reliable new pick-up assembly, a trick timing adjustment mechanism and top it off with an all new MSD distributor cap. The pick-up is an advanced optical encoder, a different style of optical pickup than the OEM. This type of pick-up has proven to be very reliable and stable through extreme rpm and conditions. The rotor is bolted to a drive assembly that is indexed to the shaft and is stabilized through the use of a large ball bearing assembly. Once installed, you have the ability to adjust the ignition timing. The only distributor that offers timing adjustability. An adjustment screw allows the timing to be tweaked up to 5 degrees. The distributor is equipped with a fresh air vent and has an extra thick mounting surface for the cap to eliminate leaks. The distributor is supplied complete with our heavy duty LT1 cap, rotor and the components required for installation.

Product Features:

• Advanced optical encoder trigger design for accuracy/reliability.
• Rotor drive design is positively indexed and cannot slip.
• Large ball bearing stabilizes timing through 10;000 rpm.
• Improved housing design and extra bolt eliminates leaks
• Easily Adjust The Timing Up To +/-5 deg.

MSD Pro-Billet Distributors are the finest performance and racing distributors available. Every feature has been engineered to endure the rigors of high performance and racing engines. Whether cruising the streets or racing stock cars, dragsters, boats or trucks, MSD has a distributor for it. MSD uses state-of-the-art, Computer Numerical Controlled (CNC) mills and lathes to machine each housing. After a long series of precise cuts and movements, the billet is formed into a flawless distributor housing that is accurate to within 0.001″. The flex-free housings are lightweight, have no porosity or weak areas and look great on polished, show quality engines.

GM late-model performance enthusiasts will be happy to see this Pro-Billet distributor. The distributor, PN 8366, is a drop-in. Replacement for GM V8s using the small cap distributor with a dual connector coil found in cars from 1987-1993 and trucks from 1987 to 1995. The entire housing is CNC-machined to exact tolerances for incredible strength (Not to mention cool looks). For improved lubrication there is an extra oil tract machined into the bottom of the housing that delivers oil directly to the cam and distributor gears. Inside, a polished steel shaft receives guidance from a sealed ball bearing and an extra-long sintered bushing adds stability. This 0.500 In. shaft also receives a QPQ coating for increased friction reduction and corrosion resistance. A factory-style ignition module is supplied with the distributor so your factory wiring will plug directly in triggering this module is the responsibility of a high output magnetic pick-up.
