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-10-6C come with a cap, rotor, and coil?
Yes. The EP-10-6C 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.
How do I verify the EP-10-6C is the correct AMC V6 distributor for my vehicle?
The EP-10-6C replaces AMC V6 distributors identified by OEM 3921397 or 3238876. Locate the OEM number stamped or labeled on your existing distributor housing. If it matches 3921397, the EP-10-6C is the correct replacement. For other AMC six-cylinder applications, see EP-10-6A (AMC 258 I6) and EP-10-6B (AMC 292 V6).
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-10-6C 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.
