Tall Block Crank Trigger Chevy V8 Distributor
Low-profile, tall block, racing distributor, must be used with an MSD 6, 7 or 8-series ignition and a crank trigger.
Overview
The unique design of these distributors fit 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 which
have been designed into these low-profile distributors. 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 Tall Block Distributor has a unique slip collar design. This allows the PN 8558 to fit in most tall block engines that have had the deck height modified.
Features:
- Designed to fit low in the block to clear firewall and intake combinations
- Supplied with bronze gear
- Supplied with large diameter HEI style distributor cap and rotor
- Must be used with an MSD Crank Trigger and MSD Ignition Control
- 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 mounting flange for engines with modified deck heights
- CNC machined billet aluminum housing and Dupont Rynite base
