The EP-2085A is an electronic distributor for Ford 351 and 400 CID V8 engines in the 1975-1989 production period -- the Duraspark and early EEC era of Ford ignition systems. Ford introduced the Duraspark electronic ignition system in 1975, replacing the previous points-based system. The EP-2085A provides a replacement for the electronic distributor used in this era's F-series trucks, LTD sedans, Gran Torinos, and Mercury full-size vehicles.
The 351 and 400 CID Ford V8 family is spread across two distinct block designs in this period: the 351 Windsor (used in F-series trucks and passenger cars) and the 351 Cleveland/400M (used in midsize passenger cars and some truck applications). These engines have different distributor shaft depths and specifications. The EP-2085A catalog listing covers the 1975-1989 range -- verify the exact engine type and OEM number to confirm fitment for your specific application.
Ships complete with cap and rotor.
