The EP-302HEA-2 is a complete HEI distributor for the Ford 351 Windsor — one of the most durable and popular Ford V8 engines ever produced, powering Mustangs, Torinos, and F-series trucks from 1969 through the late 1990s. The 351W is a beloved engine in the Ford performance community for its broad power potential and excellent aftermarket support, and HEI ignition conversion has become increasingly popular as a simplification and performance upgrade for these engines.

The 351 Windsor has a longer distributor shaft than the 289/302 small block, requiring a specific distributor designed for the Windsor deck height. The EP-302HEA-2 is dimensioned specifically for the 351W to ensure correct rotor-to-cap terminal geometry and proper drive gear mesh at the camshaft. Installing a 302-dimensioned distributor in a 351W application results in incorrect shaft depth and potential timing instability.

Manufactured under ISO 9001:2015 quality management with dimensional verification for Ford 351W shaft length and drive gear specification.

Key features

351 Windsor specific dimensions

Designed for the longer distributor shaft depth of the Ford 351 Windsor engine. Not interchangeable with the 289/302 unit (EP-302HEA-1) due to different shaft length.

Mustang and F-series coverage

Covers the 351W across the Mustang Mach 1, Boss 351, Torino, and F-series truck applications that used this engine for nearly three decades.

65K coil for Windsor performance

The 351W has excellent performance potential. The 65,000-volt coil supports modified Windsor combinations with larger carburetors and performance camshafts.

Complete HEI conversion assembly

Ships with coil, blue cap, rotor, module, and vacuum advance — everything for a complete 351W HEI conversion.

Application scenarios

Mustang Mach 1 and Boss 351 restoration

Mach 1 and Boss 351 owners converting from points or Duraspark to HEI choose the EP-302HEA-2 for performance reliability in these landmark Mustang models.

F-series 351W truck upgrade

F-150 and F-250 owners with the 351W appreciate the simplified wiring and improved cold-start reliability of the HEI system for year-round truck use.

351W specialist supply

Shops specializing in Ford performance vehicles stock the EP-302HEA-2 as the correct 351W HEI distributor, distinct from the 302 unit.

Installation guide

Same basic procedure as EP-302HEA-1, but designed specifically for the 351 Windsor deck height. Disconnect battery, mark positions, remove old distributor, lower EP-302HEA-2 to the correct depth for the 351W, connect BAT wire and vacuum hose, set timing. Do not substitute this unit for a 289/302 distributor — the shaft lengths differ. Approximately 30-45 minutes.

Frequently asked questions

What are the symptoms of a failing HEI distributor?
Common symptoms include hard starting, engine misfires at high RPM, rough idle, loss of power under load, and occasional stalling. A failing HEI module (the most common failure component) typically causes complete spark loss when hot — the engine starts fine when cold, stalls after reaching operating temperature, and may restart after a cool-down period. A worn HEI cap with carbon tracking between towers causes crossfire and cylinder-specific misfires that worsen as the cap deteriorates.
Does the EP-302HEA-2 come with a cap, rotor, and coil?
Yes. The EP-302HEA-2 ships as a complete ready-to-run assembly including the distributor housing, 65,000-volt high-output ignition coil, distributor cap with brass terminals, rotor, ignition module, adjustable vacuum advance canister, and hold-down hardware. No additional ignition components are required for installation.
What is the difference between the 351 Windsor (EP-302HEA-2) and 351 Cleveland (EP-302HEA2C) HEI distributors?
The Ford 351 Windsor and 351 Cleveland are completely different engines with different block architecture, distributor drive locations, and shaft dimensions. The EP-302HEA-2 fits the 351 Windsor engine used in Mustangs, Torinos, and F-series trucks from 1969 onward. The EP-302HEA2C fits the 351 Cleveland and its derivatives (400M, 429, 460) used in Torinos, Thunderbirds, and Lincoln Continental Mark series. Verify your engine type by checking the engine code on the VIN or the casting numbers on the block before ordering.
Is the EP HEI distributor compatible with aftermarket ignition boxes such as MSD?
EP HEI distributors with a magnetic pickup (Ready-to-Run style) are compatible with external ignition boxes including MSD 6-series, 7-series, and 8-series units, as well as equivalent ignition boxes from Mallory, Crane, and Holley. Standard HEI distributors with an internal module operate as standalone units and do not require an external ignition box, though they can be paired with one for additional timing control. Consult the ignition box manufacturer's instructions for the correct connection procedure.
How do I order the EP-302HEA-2 for export or wholesale?
EP supports single-unit orders for market sampling, carton quantities for repair shops, and container-volume wholesale orders. Standard production lead time is 15-30 days. OEM branding, private-label packaging, and custom color selection are available for qualifying volumes. Contact our team via the inquiry form or WhatsApp for pricing and availability.
