1987 Buick Regal Performance Distributors

The MSD 8410 GM HEI Distributor Rotor is a premium, high-quality stock replacement component engineered by MSD Performance to deliver maximum electrical conductivity and unwavering spark reliability for classic and modern GM HEI ignition systems.

The MSD 84101 Extreme Output GM HEI Distributor Rotor is a premium, high-voltage replacement component engineered by MSD Performance to withstand the punishing demands of high-output modules and maximum racing RPMs.

The cap and rotor of any ignition system must be considered mainte­nance items. Just as you change the oil and filter of your car, you should always replace the cap and rotor as a set. To make things easy, we now offer these Cap and Rotor Replacement Kits.

“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.”

HyperSpark distributors are plug and play with Sniper EFI and other HyperSpark related components making it a seamless installation. Each distributor and shutter wheel are CNC billet construction to protect against high speeds and durability during drivability. Our single Hall Effect sensor guards against signal interference, keeping timing control accurate and steady. Along with plug and play ease, we include our patented clear cap for quick installation of the distributor. For best results, we offer many HyperSpark products to maximize your engine performance.

Our line of Billet Plug n€™ Play Distributors are based on a precision CNC-machined housing with an upper ball bearing to support the steel distributor shaft accurately from idle to redline rpm. These distributors feature our maintenance-free Ignitor II or III electronic ignition module to produce a strong spark and steady ignition timing.

TSP HEI Distributor has everything you need, all under one cap. With a high-quality aluminum housing and hardened steel dual bushing construction, it is built to last. It features fully adjustable mechanical and vacuum advances, meaning precision is a breeze. It has a high-output module, high-spark 65,000 volt coil, solid brass terminals, and an easy one-wire hookup.

ACCEL Performance Replacement Distributors are the perfect choice for your daily driver or street machine. Using all new components, these distributors feature High-performance ACCEL Electronics. All new components-housings are either new castings or turned from billet stock, centerless ground shaft with oil lite bushings. High dielectric strength cap, balanced rotor. Male tower distributor cap with brass cap and rotor contacts (Ford and AMC Models feature screw-mounted wire retainer for the ultimate plug wire retention). Iron or steel distributor gear. Direct plug-in replacement with factory-type connectors for plug and play installation.

This distributor uses a high-output magnetic trigger to fire an MSD Ignition Control. Accurate trigger signals and spark delivery are the responsibility of the QPQ-coated steel shaft. A sealed ball bearing and long sintered

These distributors feature our maintenance-free Ignitor II or III electronic ignition module to produce a strong spark and steady ignition timing.

A legend returns – the tried and true Mallory Unilite Distributor line is back! The easy three wire hookup of the Unilite makes running a stock coil, a Mallory performance coil and even a Mallory HyFire CD ignition a snap. Supplied with a quality cap and rotor, the Mallory Unilite also provides a fully adjustable mechanical advance to dial in the perfect timing curve for a multitude of engine combinations. The Unilite features a compact housing that lends itself well to applications where space is a premium due to tight firewall clearance or blower applications.

Note: The PN 8365 is designed to replace GM HEI Distributors that use a 4-pin ignition module.

Flame Thrower Street/Strip distributors have a speciallFlame-Thrower Street/Strip distributors have a specially designed HEI distributor module and coil combination which operates without misfire beyond 7500 RPM. That’s nearly 3000 RPM higher than most stock HEI Distributors. Race HEI Distributors feature an electronic HEI Distributor module and 50,000 volt coil combination that optimizes spark energy and peak current to the spark plug in the 6000 to 8500 RPM range.y designed module and coil combination which operates without misfire beyond 7500 RPM

MSD Ignition has put a great deal of effort into researching and testing a variety of metallurgical compositions, heat treating and coatings to provide you with a durable, accurate and strong distributor gear. MSD engineers have built test fixtures and spent hundreds of hours testing and evaluating the metallurgy of our gears. The result is a special iron alloy gear that is treated to a low-friction coating process. To you this means long life, an easy break-in period and reliable performance.

One of the best, and sometimes missed tuning tricks is not to just optimize your initial timing, but to bring in timing advance more quickly than the stock distributor can allow. Bringing timing more quickly than stock can provide substantial increases in both torque and horsepower depending on your combination.This is done by changing the springs under the cap. This kit includes three sets of springs which can be used in different combinations to provide full advance sooner than stock. Use lighter springs to bring the advance more quickly, and heavier springs to bring it in more slowly. Two new weights with nylon bushings are also included as are instructions to help with installation. Springs are color code as follows: Light Springs – Black Medium Springs – Silver Heavy Springs – Gold
