We evaluated the short comings of the OEM optical trigger and incorporated our own trigger wheel and digital encoder. This trigger process is much more reliable and accurate through high rpm.
❚ Advanced optical encoder trigger design for accuracy and reliability.
❚ Easily adjust the timing up to +/-5°.
❚ Improved housing design and extra bolt eliminates leaks.
❚ Fresh air vented and sealed to keep the elements out.
❚ Large ball bearing stabilizes timing through 10,000 rpm.
❚ Rotor drive design is positively indexed and cannot slip.
Finally, an all-out performance distributor to replace the OEM GM LT-1 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 pickup assembly, a trick timing adjustment mechanism and top it off with an all new MSD distributor cap! 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°. 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 LT-1 Cap, Rotor and the components required for installation.
