1987 Chevrolet Corvette 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.

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

“Fits Chevy small block and big block engines with 0.491″” shaft. Replacement component.”

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

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.

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.

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.

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.

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.

Inside, the ignition module and coil work together to produce a stout spark to light the fuel mixture for great performance. The high voltage is transferred through a new rotor to the brass terminals of the distributor cap and out to the plugs. The Street Fire Distributor is the first product to come from our new value branded ignition line.

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.

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

This strong, billet aluminum distributor is set up for engines that run locked-out timing or an MSD Timing Computer. With no advance assembly, the rotor plate is welded directly to the oversized shaft. A sealed ball bearing guides the top of the shaft while an extra long sintered bushing stabilizes the lower portion.

TSP Pro Series Ready to Run Distributor is perfect for a street performance upgrade. It features a CNC-machined billet aluminum body and hardened steel shaft, with a sealed ball bearing on top and a sintered steel bushing on the bottom. It also comes with a fully adjustable mechanical advance, vacuum advance, magnetic pickup trigger, and a high-output circuit board module with digital tach output. The dielectric cap comes with solid brass terminals and a color-matched wire retainer.
