The EP-FD04 is a complete electronic distributor for the Ford 5.0L (302 CID) V8 in 1985 EFI applications, including the Ford Bronco, early Mustang GT, and F-series trucks. The 1985 model year represents the early period of Ford's EFI conversion for the 302 V8, with the EEC-IV computer providing fuel and ignition management through the TFI distributor system.
Distributor gear material is critical for this application: the EP-FD04 uses an iron distributor gear, correct for the flat-tappet camshafts used in virtually all Ford 5.0L 302 engines through 1992. Using a steel gear distributor in a flat-tappet application will destroy the camshaft distributor drive gear. The iron gear is correct for 1985 Bronco, Mustang, and F-series applications with stock and most performance camshafts.
Note: the 1994-1995 Mustang GT 5.0L uses a hydraulic roller camshaft requiring a steel gear distributor (see EP-FD22). The EP-FD04 is for 1985 and other flat-tappet 302 applications. Ships with TFI module, cap, and rotor.
