MSD-84863 Chevy Super Tall Block Black Crab Cap Distributor

MSD-84863 Chevy Super Tall Block Black Crab Cap Distributor

Low-profile, tall block racing distributor

Features:

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

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

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.

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