EP-FD20 Distributor for Ford Bronco 1978 6.6L 400 CID V8 Duraspark

The EP-FD20 is a Duraspark electronic ignition distributor for the Ford 400M (400 CID, 6.6L) V8 engine -- the mid-displacement big block that Ford used in Broncos, F-series trucks, Thunderbirds, and Mercury Cougar through the late 1970s. The 400M (also known as the 400 Modified) is a member of the Ford 335-series engine family (alongside the 351 Cleveland and 351M), sharing the same basic block architecture but with increased displacement.

Ford introduced the Duraspark electronic ignition system in 1975, replacing the contact-breaker points system. The Duraspark distributor uses a magnetic pickup to trigger an external Duraspark ignition module, providing more consistent ignition timing than the points system it replaced. The EP-FD20 covers the Duraspark configuration for the 400M engine in the 1977-1979 period.

The Ford Bronco with the 400M V8 is particularly popular in the classic off-road community, and the EP-FD20 provides reliable distributor replacement for this specific engine and era combination. Ships complete with cap and rotor.

Every EP Ford distributor is manufactured under ISO 9001:2015 certified quality management. Each unit is individually tested for cap-to-rotor alignment, TFI module function (EFI-era units), pickup signal integrity, shaft seal condition, and distributor gear specification before shipment. CE-EMC electromagnetic compatibility certification, UL listing, and UKCA conformity confirm compliance across all major export markets. Units ship complete with cap and rotor -- TFI module included on EFI-era units where applicable.
