HolleyDAYS are here again! SAVE up to 20% on this part and hundreds of other Holley brands during the 2018 HolleyDAYS sale 11/15/18-12/31/18.

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. 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 LT1 Cap, Rotor and the components required for installation.

Installation Instructions (PDF)

  • 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.
  • For 92-94 LT1 engines, supplied with fresh air hoses.
  • Incorporates our own trigger wheel and digital encoder. This trigger process is much more reliable and accurate through high rpm.
  • For 92 Corvette owners: For a splice-free installation, get the adapter harness here.

Notes

This distributor replaces the Optispark I non-vented, spline drive style OEM distributor only. Includes components to convert to a vented distributor. If using this distributor on a 1992 Corvette please see suggested parts for recommended harness.
Some parts are not legal for use in California or other states with similar laws/regulations
