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. Thisincludes a large diameter cap with wide spaced terminals andan injection molded Rynite rotor with thick vanes to stirup the air inside the cap. Thehigh dielectric Rynite base also prevents arcing to the billet housing. The Tall BlockDistributor has a unique slip collar design. This allows thePN 8558 to fit in most tall block engines that have had the deck height modified.
