MSD's Super Tall Crab Cap distributor is taller to fit special racing blocks such as the Allen Root or Rocket blocks.

Crab Cap Distributors are built specifically for racing engines with almost no room for a distributor due to tunnel rams or blowers. The distributor is equipped with a special low-profile crab style distributor cap to allow it to fit in extremely tight areas.

The housing features two optional O-rings at the bottom that improve oil control by preventing oil pressure loss. Also, a small oil bleed hole located in the base sprays oil on the distributor and camshaft gears to prevent excessive wear. Since this is a racing distributor, there is an adjustable slip collar to make up for engines that have had the distance between the mounting surface and the gear modified.

Crowning this distributor is MSD's own Crab Cap! This cap incorporates spark plug style terminals for a better connection and grip to the plug wires while providing excellent clearance since plug wires exit the side of the cap

Features:

  • Designed to fit low in the block to clear firewall and intake combinations
  • Must be used with an MSD Crank Trigger and MSD Ignition Control
  • Supplied with small, low crab style distributor cap, rotor and bronze gear
  • O-ring seals can be added to modified blocks to improve oil pressure control
  • Special oil tract improves lubrication to the distributor and cam gear
  • Shaft is guided by a sealed ball bearing and an extra-long sintered bushing
  • Oversized polished steel shaft with a QPQ coating for friction reduction
  • Adjustable slip collar for engines with modified deck heights
  • CNC machined billet aluminum housing and durable composite base
  • 0.500” taller housing for extra tall Chevrolet based engine blocks
