EP-318C HEI Distributor for Chrysler Dodge Mopar Big Block 383-400 V8 (Replaces 3438710)

The EP-318C serves Chrysler's legendary B-series big block V8 ?? the 383 and 400 cubic inch engines that powered the Dodge Charger, Plymouth Road Runner, and GTX during the golden era of American muscle. The 383 Magnum was the standard performance engine in the Charger and Road Runner, while the 400 was a popular choice in late B-body applications. These engines are at the heart of some of the most sought-after muscle cars in the world, and reliable ignition is essential for both restoration and serious driving use.

The Chrysler B-series big block has a unique distributor configuration distinct from both the Mopar LA small block and the RB big block (426 Hemi and 440). The EP-318C is correctly dimensioned for the B-series block distributor location and drive system, ensuring proper shaft depth and drive gear mesh for reliable ignition timing.

Manufactured under ISO 9001:2015 quality management with dimensional verification for Chrysler B-series big block distributor specifications.

Every EP HEI distributor is manufactured under ISO 9001:2015 certified quality management. Each unit is individually tested for ignition coil output voltage, electronic module switching function, vacuum advance response, and shaft seal integrity before shipment.
