The EP-3M is a Ready-to-Run electronic distributor for Holden V8 engines -- the 253 and 308 cubic inch powerplants that defined Australian performance motoring across the Kingswood, Monaro, Torana, and early Commodore platforms from the late 1960s through the mid-1980s. The Holden 308 is one of the most respected Australian V8 engines, and the transition from points ignition to modern electronic ignition is the most popular and effective reliability upgrade in the active Holden V8 enthusiast community.

EP exports the EP-3M directly to Australian and New Zealand aftermarket distributors. With genuine Holden factory parts no longer available through dealer networks following the closure of Holden's Australian operations, the EP-3M fills the gap with a quality aftermarket Ready-to-Run distributor engineered to Holden-specific dimensions. The Holden V8 requires its own specific distributor design -- not a modified American V8 unit -- and the EP-3M is correctly dimensioned for Australian application.

The two-wire installation is simpler than most factory Holden ignition wiring, and the maintenance-free magnetic pickup eliminates the periodic points adjustment that has always been a feature of classic Holden V8 ownership. An external coil is required, allowing the builder to choose coil specification to match the engine tune.

Frequently asked questions

What is the difference between a Ready-to-Run distributor and an HEI distributor?
A Ready-to-Run (R2R) distributor integrates an electronic ignition module inside the distributor housing but retains an external ignition coil connected via two wires. An HEI distributor integrates both the module and the coil directly inside the large-diameter cap, requiring only a single 12-volt wire. R2R distributors are more compact and better suited to engine bays with limited clearance, or to builders who prefer to keep their existing external coil. HEI distributors are simpler to wire but have a larger footprint. Both replace worn points-type ignition with a maintenance-free magnetic pickup.
What does the EP-3M ship with?
The EP-3M ships as a complete ready-to-install assembly including the distributor body, internal high-output ignition module, distributor cap with solid brass terminals, rotor, and adjustable vacuum advance canister. An external ignition coil is required but not included -- EP recommends pairing with a quality 40,000-volt or higher external coil for best results. Two-wire installation: connect the +12V switched power wire and the coil negative trigger wire.
Does the EP-3M fit both the Holden 253 and the 308 V8?
Yes. The Holden 253 and 308 V8 engines share the same basic block architecture and distributor drive configuration. The EP-3M fits both displacements across HQ, HJ, HX, HZ Kingswood, Monaro, Torana, WB Statesman, and early Commodore VB/VC applications. The distributor shaft dimensions and drive gear are consistent across both Holden V8 displacements.
Can a Ready-to-Run distributor be used with an external MSD or other ignition box?
Yes. Ready-to-Run distributors with a magnetic pickup are fully compatible with external ignition amplifiers including MSD 6-series, 7-series, and 8-series units, as well as equivalent boxes from Mallory, Crane, and Holley. When pairing with an external ignition box, the internal module in the R2R distributor acts as the trigger signal source while the ignition box handles spark amplification. Consult the ignition box manufacturer's wiring instructions for the correct connection procedure for distributor-triggered systems.
How do I order the EP-3M 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.
