Check Vehicle Fit

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 +/-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 LT1 cap, rotor and the components required for installation.

Product Features:
  • Advanced optical encoder trigger design for accuracy and reliability
  • Easily adjust the timing up to +/-6°
  • Uses own trigger wheel and digital encoder
  • Fresh air vented and sealed to keep the elements out
  • Large ball bearing stabilize

Comments about MSD Ignition Distributor, 95 to 97 General Motors LT-1 5.7L:

I personally installed this unit in my 1995 Chevrolet Camaro Z28. I wanted more reliability than OE had to offer, once my stock distributor died on me. This is a great alternative to the OE GM Opti-Spark. Installation was a little cumbersome, however the results were well worth the challenge. The incorporation of extra bolts (which hold the unit together) has eliminated possible leaks into the system, which all so often caused optical failure. The addition of being able to +5/-5 degrees on the timing of this unit, has allowed me to not only increase my power, but save on fuel economy.
