1993 Buick Roadmaster Performance Distributors

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.

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.

Product Features:

• Drop-in billet replacement for GM dist. w/small cap/external coil
• Factory style ignition module accepts factory wiring
• CNC machined billet aluminum housing and billet aluminum base
• Maintenance-free magnetic pickup and precision reluctor
• Oversized steel shaft is QPQ coated
• Guided by sealed ball bearing and an extra long sintered bushing
• Special oil tract improves lubrication to the dist./cam gear
• O-ring seals can be installed for oil press. control (Mods only)
• Supplied w/Late Model Distributor Cap And Rotor
• Legal to install in all 50 states
