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.

HZPT is the international brand of Ningbo Xianlong Automobile Fittings Co., Ltd., established 1999. With over 25 years of distributor manufacturing experience, EP provides the automotive aftermarket with reliable OEM-specification replacement distributors for GM vehicles from the classic EFI era of the late 1980s through the mid-1990s -- a period when millions of C/K trucks, Blazers, Suburbans, and passenger cars were built with distributors that have now accumulated 30 or more years of service and are approaching or past their reliable service life.

EP ignition distributor production line

Each EP GM Distributor ships as a complete plug-and-play assembly -- distributor body, cap, rotor, and all sensors -- ready for direct installation without modification. Reference OEM part numbers are provided for fitment verification. EP is part of the Ever-Power Group, also producing worm reducers and a comprehensive range of mechanical transmission products.

Frequently asked questions

What are the symptoms of a failing GM EFI distributor?
Common failure symptoms for GM EFI distributors of this era include intermittent no-start conditions, engine stalling at operating temperature, erratic idle quality, loss of power under acceleration, and check engine codes related to the distributor reference signal or cam position sensor. The Vortec-era distributors (1996-2002) are particularly known for plastic housing cracking or warping from heat cycling, which allows oil or coolant contamination of the optical or magnetic pickup sensor inside the housing. The LT1 Optispark distributors (1992-1994) are known for moisture infiltration that degrades the optical sensor window, typically producing a characteristic hard cold-start condition that improves as the engine warms up.
Does the EP-2085A ship with the cap, rotor, and all necessary sensors?
Yes. The EP-2085A ships as a complete plug-and-play assembly including the distributor body, distributor cap, rotor, and all internal sensors required for operation in the listed applications. For Optispark LT1 units, the optical sensor assembly is included as part of the complete distributor. For standard EFI units, the magnetic pickup and cam position reference sensor are integrated into the assembly. No additional ignition components are required beyond the standard ignition module and coil already present on your vehicle.
How do I identify whether my Ford 351 is a Windsor or a Cleveland for EP-2085A fitment?
The 351 Windsor (351W, 1969-present) has narrow, upright valve covers with 6 bolts per side and a narrow valve cover bolt pattern. The 351 Cleveland (351C, 1970-1974) and 400M (1971-1982) have wide, angled valve covers with 8 bolts per side. The Cleveland was discontinued in 1974 passenger car applications; most F-series truck 351 applications from 1975 onward use the Windsor. Check your valve cover style to identify the engine family, then verify the OEM distributor number for exact fitment.
Do I need to reset the timing after installing this distributor?
For most GM EFI applications of this era, the distributor does not require timing adjustment after replacement if the engine is set to top dead center (TDC) before the old distributor is removed and the new unit is installed in the same position. Most 1987-1995 GM TBI and EFI applications use a computer-controlled timing advance that does not require a timing light for replacement -- align the distributor housing marks and the rotor to the same position as the original unit. For 1992-1994 LT1 Optispark applications, the base timing is not adjustable in the field; the Optispark provides a crankshaft-referenced timing signal and the PCM controls all timing advance. Consult the factory service manual for your specific vehicle year and engine for the correct installation procedure.
How do I order the EP-2085A for export or wholesale?
EP supports single-unit orders for market sampling, carton quantities for repair shops and parts counters, and container-volume wholesale orders. Standard production lead time is 15-30 days. OEM branding and private-label packaging are available for qualifying volumes. Contact our team via the inquiry form or WhatsApp for pricing and availability.
