The MSD Ford 351W Crank Trigger distributor shares the same low-profile design as MSD's other Crank Trigger distributors, with a Rynite-molded Ford-style cap and wire retainer that clears busy intake setups since only a rotor sits under the cap. It has no advance assembly or pickup, so it must run with an MSD Crank Trigger and an MSD 6, 7, or 8-series Ignition Control. A ball bearing guides the polished, QPQ-coated steel shaft, and a bronze gear is included for race applications. The standard-height Ford housing and Dupont Rynite base work with cast intake manifolds.
