GMC C25 Performance Distributors

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

The street Pro-Billet is a popular route for people looking for proven race performance for their street cars. A vacuum advance canister provides economy and the proven MSD mechanical advance gives you the opportunity to dial-in a timing curve to fit your needs. Inside, an oversized steel shaft is QPQ coated for low friction and rides in a sealed ball bearing at the top of the distributor with an extra-long sintered bushing at the bottom. This combination keeps the shaft steady creating accurate spark delivery at any RPM. The street Pro-Billet relies on a magnetic pick-up to trigger the MSD Ignition control which delivers the powerful sparks to the coil. This pick-up is extremely accurate and never needs adjusting.

Introducing the Street Fire value-line brand of MSD Ignition. Street Fire components offer a quality designed alternative to the bottom bargain parts that are springing up all over. We’re so assured with the quality of our new Street Fire HEI distributor that we provide a one year warranty with it! We know the importance of a centrifugal advance in a distributor so our engineers made sure that the Street Fire receive an advance assembly with coated weights and welded weight pins (Not just pressed in like other models). Another area that you cannot afford to scrimp on is with a distributor gear. The Street Fire is fit with the same gear that is used on our Pro-Billet models. The metallurgy of this gear has been refined for years to perform through the harshest conditions. Inside, the ignition module and coil work together to produce a stout spark to light the fuel mixture for great performance.

Product Features:

• Included 4-Pin Module
• The only value priced HEI with a full one year warranty
• Heavy duty distributor gear for durability
• Welded weight pins and heavy duty construction
• Adjustable vacuum advance helps tune it to each engine
• 21° of mechanical advance

Add sparkle to your engine with this chromed hold-down clamp. With bolt and gasket. Serrations on the bottom prevent distributor and magneto rotation for accurate timing.

Product Features:

• Rolled Edges For Strength
• Ideal For Magnetos
• Ideal For Ignition Distributor

Product Features:

• Heavy Duty Cap and Rotor Kit
• With Brass Inserts

ACCEL cap and rotor kits offer superior protection from “arc-thru” and crossfire. Features 60k V-rated alkyd compound, stress-relieved at molding to ensure stability. Brass inserts and steel rotor springs provide for high spark energy flow.

Product Features:

• See catalog for application information
• Features 60K V Rated Alkyd Compound

With the introduction of our 20 Amp extreme HEI module, we needed an HEI cap and rotor that could withstand the high output. The answer was to mold our own HEI cap, rotor and coil cover. The cap and rotor will fit our HEI Pro-Billet distributor, PN 8365, plus will work on stock applications.

Product Features:

• Extreme output rotor

ACCEL Hi-Performance rotors offer superior protection from arc-thru and crossfire. Features hi-performance 60,000 volt alkyd compound, stress-relieved at molding to ensure stability and resist centrifugal forces at high racing RPMs.

Product Features:

• Max stability for all RPM ranges
• Heavy duty for maximum energy transfer
