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 degrees. 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/reliability.
