MSD 83811 Pro-Billet LT1 Distributor
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 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. Once installed, you have the ability to adjust the ignition timing - the only distributor that offers timing adjust ability. An adjustment screw allows the timing to be tweaked up to +/-
