Chevy w/Crab Cap HEI-Style
Billet Crank Trigger Distributor with Low-Profile Housing
  • Fits 1955-1975 Chevy Small Block and Big Block V8 Engines
  • Requires a Crank Trigger and a 6, 7 or 8 Series Ignition Control
  • Bronze Distributor Gear
  • Cap and Rotor Included

    Tall intakes, tight firewalls and hood clearance problems are a fact of life in a race car, and a standard distributor often will not fit. This unit sits low in the block to clear those combinations while still carrying the high voltage of a racing ignition to the plugs. Because it is crank triggered, the distributor only distributes spark, so timing accuracy comes from the crank trigger rather than the distributor shaft.

    MSD 846973 Low-Profile Crank Trigger Distributor Features:

    • Designed to fit low in the block for firewall and intake clearance.
    • Must be used with a crank trigger and a 6, 7 or 8 Series ignition control.
    • Oversized polished steel shaft with QPQ coating, guided by a sealed ball bearing and extra long sintered bushing.
    • Supplied with a bronze gear for use with aftermarket camshafts.
    • Large diameter HEI style cap and rotor included.
    • Black anodized CNC billet aluminum housing.

    Emissions Note:

    This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.

    • Distributors Geared for Racing

      MSD Ignition Crank Trigger distributors are designed for racing engines that use a crankshaft triggered ignition. A low profile lets these distributors fit in tight quarters and still accurately deliver the sparks. Each crank trigger distributor contains a CNC-machined billet aluminum housing and inside the housing, a sealed ball bearing and long sintered bushing, guide a QPQ-coated shaft for accurate spark delivery throughout high rpm. A low profile distributor cap with brass terminals clamps onto the housing and covers the racing rotor. The rotor contains deep vanes to stir up the air; reducing the chance of spark scatter. Since these distributors are for racing applications, bronze gears are supplied. Must be used with an MSD Crank Trigger and MSD 6, 7 or 8-Series Ignition Control
