The EP-8579 is a Ford 289-302 HEI distributor with an integrated tachometer output for applications requiring an electronic tachometer signal alongside HEI ignition operation. While the EP-302HEA-1 serves standard Ford 289/302 applications, some Ford vehicles and custom builds require a specific tachometer output terminal on the distributor to drive an electronic gauge cluster or external tachometer. The EP-8579 provides this tach output while delivering full HEI ignition performance.

The 'EACH' designation in the catalog description refers to the individual-unit pricing and specification for this tachometer output variant. Ford performance builders installing aftermarket gauge clusters, racing tachometers, or data acquisition systems frequently require a clean tachometer signal direct from the distributor. The EP-8579 provides this signal without requiring an external tachometer adapter or signal converter.

Manufactured under ISO 9001:2015 quality management with tachometer output signal verification alongside standard coil and module testing.

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-8579 come with a cap, rotor, and coil?
Yes. The EP-8579 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 EP-8579 and the EP-302HEA-1 for the Ford 289-302?
The EP-302HEA-1 is the standard Ford 289/302 HEI distributor without a dedicated tachometer output terminal. The EP-8579 adds an integrated tachometer signal output for connecting electronic tachometers, aftermarket gauge clusters, or data logging equipment directly to the distributor. If your Ford application uses an electronic tachometer that requires a distributor input signal, choose the EP-8579.
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-8579 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.
