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.
