Chevy w/HEI-Style Terminals
The unique design of this distributor fits tight intake systems while still transferring the high voltage of the MSD racing ignition to the spark plugs. The high voltage carrying capabilities are the result of several features that have been designed into this distributor. This includes a large diameter cap with wide-spaced terminals and an injection-molded Rynite rotor with thick vanes to stir up the air inside the cap. The high dielectric Rynite base also prevents arcing to the billet housing. The distributor has an oversized steel shaft that is guided with a sealed ball-bearing assembly and extra-long sintered bushing for smooth operation.
- Designed to fit low in the block to clear firewall and intake combinations

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
