83811 Pro-Billet Distributor

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 Degree. 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. Features Advanced Optical Encoder Trigger Design For Accuracy And Reliability.
