EP-9-1 Pro Billet Distributor for Ford 351 Windsor V8 — CNC 6061-T6 Race Ignition

The EP-9-1 is a CNC-machined 6061-T6 billet aluminum Pro Billet distributor for the Ford 351 Windsor -- one of the most enduring and respected Ford V8 engines, produced continuously from 1969 through the late 1990s and powering race-winning Mustangs, Torinos, and F-series trucks. The 351W is a popular basis for serious performance builds due to its robust bottom end and extensive aftermarket cylinder head and induction support, and the EP-9-1 delivers the billet-quality ignition trigger accuracy these builds demand.

The EP-9-1 is dimensioned specifically for the 351 Windsor's shaft depth -- it is NOT interchangeable with the 351 Cleveland or 289/302 small block. The Windsor's longer deck height requires a distributor with the correct shaft length for proper reluctor depth and drive gear engagement. Installing a 289/302 or Cleveland-dimensioned billet distributor in a 351W will result in incorrect shaft depth, timing instability, and rapid drive gear wear.

Like all EP Pro Billet distributors, the EP-9-1 requires an external ignition box (MSD 6A, 6AL, 7AL-2, 8-Plus, or equivalent) and an external coil. The magnetic pickup trigger signal can drive any standard magnetic-pickup-compatible ignition box, giving the builder full flexibility in ignition system choice regardless of brand.

Every EP Pro Billet distributor is machined from 6061-T6 aerospace-grade billet aluminum under ISO 9001:2015 certified quality management. Each unit is individually tested for magnetic pickup signal accuracy, mechanical advance travel range, shaft concentricity, and housing dimensional compliance before shipment. CE-EMC electromagnetic compatibility certification, UL listing, and UKCA conformity mark cover all units across our major global export markets.

Founded in 1999 in Ningbo, Zhejiang Province, EP operates CNC machining centers and automated production lines dedicated to automotive ignition components. The Pro Billet series is machined from aerospace-grade 6061-T6 aluminum billet -- the same alloy designation used by MSD, Speedmaster, and Pertronix in their own billet distributor lines -- on modern CNC mills and lathes producing tolerances of ±0.001 inch or better throughout the housing.

Each Pro Billet distributor features an oversized hardened steel shaft supported by a top-mounted sealed ball bearing and extra-long sintered steel bushing, delivering precise rotor-to-terminal geometry at sustained operation above 8,000 RPM. The adjustable mechanical advance assembly ships with multiple spring and bushing sets for custom advance curve configuration. EP is part of the Ever-Power Group, also producing planetary gearboxes and a comprehensive range of mechanical transmission products.
