EP-11 Pro Billet Distributor for Ford 289 302 Late EFI Windsor V8 — CNC 6061-T6

The EP-11 is a CNC-machined 6061-T6 billet aluminum Pro Billet distributor for the Ford 289 and 302 Windsor V8 in late EFI and hydraulic roller camshaft applications. The critical distinction between the EP-11 and the EP-289VWMG (the standard 289/302 Pro Billet unit) is the distributor gear material: the EP-11 uses a steel gear compatible with the factory hydraulic roller camshafts introduced in Ford 302/5.0L engines from approximately 1985 onward, while the EP-289VWMG uses an iron gear suited to flat-tappet applications.

Ford's factory hydraulic roller camshaft introduced in the 5.0L High Output engine requires a steel distributor gear rather than the traditional iron gear used with flat-tappet cam grinds. Using an iron gear distributor with a steel roller cam results in rapid cam gear wear that can destroy the camshaft within a few thousand miles. The EP-11 is the correct choice for any 289 or 302 build -- street performance or race -- that uses a factory 5.0L HO roller cam, an aftermarket hydraulic roller camshaft, or an EFI-equipped 302/5.0L engine with the factory roller valvetrain.

The EP-11 requires an external ignition box and external coil. For Fox body Mustang 5.0L builds running MSD or Holley ignition systems, the EP-11 provides billet-quality trigger accuracy with the correct gear specification for roller cam engines.

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 couplings and a comprehensive range of mechanical transmission products.
