Overview

The MSD 8381 is a performance distributor designed to replace the OEM GM LT1 Optispark. It features a billet aluminum housing, an advanced optical encoder pick-up assembly for accuracy and reliability, and a timing adjustment mechanism that allows for +/- 5° of timing adjustment. The distributor is equipped with a fresh air vent and has an extra thick mounting surface to eliminate leaks. A large ball bearing stabilizes timing through 10,000 rpm, and the rotor drive is positively indexed to prevent slipping.

Part #: 8381

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.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 distributor is supplied complete with our heavy duty LT1 Cap, Rotor and the components required for installation.Once installed, you have the ability to adjust the ignition timing - the only distributor that offers timing adjustability!
