Ford 351W V8 EFI to Carb Conversion HEI Distributor

• Internal 65,000V coil delivers stronger spark for 351W ignition

• One-wire hookup — no external coil or ignition box required

• Built for Ford 351W EFI-to-carb conversion swaps

• Machined aluminum housing with adjustable mechanical/vacuum advance

Convert your factory-EFI Ford 351 Windsor (351W) V8 to a carbureted ignition system with this HEI-style distributor, built around a magnetic trigger and a 65,000-volt coil housed directly in the unit — so there's no external coil or ignition box to wire in separately. The one-wire hookup simplifies installation on F-Series, Bronco, E-Series, and Lightning applications.

This distributor uses a longer gear/shaft configuration built specifically for EFI-to-carb conversions and is not intended for engines that came carbureted from the factory; it will not fit 351C, 351M, or the smaller Windsor displacements (221, 260, 289, 302). The housing is machined aluminum with a steel drive gear best matched to cast iron hydraulic or solid flat-tappet camshafts, and rotation is counterclockwise. This distributor requires a 12-volt electrical system with an alternator; it is not compatible with generator-based charging systems or vehicles still running an active ballast resistor in the ignition circuit — the resistor should be removed or bypassed as part of installation.

What Is an HEI EFI-to-Carb Conversion Distributor?
HEI (High Energy Ignition) replaces the factory EFI ignition control with a magnetic trigger and a high-output coil built directly into the distributor housing, so there's no external coil or ignition box to wire in. Because this unit is purpose-built for EFI-to-carb conversions, it uses a longer gear/shaft configuration than a standard factory-carbureted 351W distributor and is not designed to fit engines that came carbureted from the factory.

Performance Benefits
The 65,000-volt internal coil produces stronger, more consistent spark output than the factory EFI ignition module it replaces, supporting steady combustion through the RPM range after the carburetor conversion. The magnetic trigger holds timing accurately without the wear-related drift of a points-based system, and the adjustable mechanical/vacuum advance lets the timing curve be tuned specifically for the conversion rather than relying on the factory EFI timing tables.

What's the difference between this and the standard 351W HEI distributor?
This version is designed specifically for EFI-to-carburetor conversions and uses a longer distributor shaft and gear than the standard carbureted 351W HEI distributor. It is not intended for 351 Windsor engines that came carbureted from the factory.

Will this fit a 351 Cleveland or 351 Modified?
No. This distributor is designed specifically for the Ford 351 Windsor (351W) and is not compatible with 351 Cleveland (351C) or 351 Modified (351M) engines.

Will this fit a 302 or other small Windsor engine?
No. This distributor is built exclusively for the 351 Windsor (351W) and will not fit 221, 260, 289, or 302 Windsor engines.

Do I need an external ignition box with this distributor?
No. This distributor features an integrated 65,000-volt ignition coil and internal ignition module, so no external ignition box or separate coil is required. Installation requires only a switched 12-volt power connection.

What direction does the rotor turn on this distributor?
Counterclockwise, viewed from above, matching the standard rotation direction of the Ford Windsor V8 family, including the 351W.

What type of distributor gear is included, and will it work with my camshaft?
This distributor includes a steel distributor gear, which is best suited for cast iron hydraulic or solid flat-tappet camshafts. If your engine uses a roller or other specialty camshaft, verify the recommended distributor gear material with your camshaft manufacturer before installation.
