Blue oval racers will be happy to see these Crank Trigger Distributors. The housing of these three distributors are standard-height Ford Distributors so they will work with cast intake manifolds. These distributors have a low-profile cap assembly to clear busy intake set-ups and are topped with MSD's new Rynite-molded Ford-style cap and wire retainer. The low design is accomplished because the only thing under the cap is a rotor! These distributors don't have an advance assembly or pick-up so they must be used with a Crank Trigger. Since these distributors are designed for racing applications, a ball bearing is pressed into the housing to guide the polished steel shaft. Each distributor is supplied with a bronze gear.
