MSD Part Number 84863
Fits Big Block Chevy Super Tall Deck Engines
Low-profile, tall block, racing distributor must be used with an MSD 6, 7 or 8-series ignition and a crank trigger.
The
super tall crab cap is taller to fit special racing blocks such as the
Allen Root or Rocket blocks.
The MSD 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.
