Pro-Billet Optispark Distributor (’93-’94 LT1)
Finally, an all-out performance distributor to replace the problematic OEM GM Optispark! MSD starts with an entire billet block of aluminum and machines it down into a precise housing that fits in place of the factory piece. Then, install a reliable new pickup assembly, a trick new timing adjustment mechanism and top it off with an all new MSD performance rotor and distributor cap. The result is a damn near bulletproof unit known as the Pro-Billet OptiSpark.
The pickup is an advanced optical encoder, a different style of optical pickup than the OEM. This style pickup 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°. Finally, the distributor is equipped with a fresh air vent and has an extra thick mounting surface for the cap to eliminate leaks.
The Pro-Billet OptiSpark comes supplied complete with MSD’s heavy duty LT1 Cap, Rotor and the components required for installation
Fitment includes: 93-94 Corvette, 93-94 Camaro/Firebird equipped with LT1 engine.
