The MSD-8381 GM LT1 5.7L 92-94 Distributor is an all-out performance distributor to replace the OEM GM LT1 Optispark. An entire billet block of aluminum is machined down into a precise housing that fits in place of the factory piece. It is then filled with a reliable new pick-up assembly, timing adjustment mechanism, and 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°. 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 a heavy duty LT1 Cap, Rotor and the components required for installation.

• Advanced optical encoder trigger design for accuracy and reliability
• Rotor drive design is positively indexed and cannot slip
• Large ball bearing stabilizes timing through 10,000 rpm
• Fresh air vented and sealed to keep the elements out
• Improved housing design and extra bolt eliminates leaks
• Easily adjust the timing up to +/-5°
