Description

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.
