Product Details
Features
- Onboard ignition module — no separate ignition box required
- Built for Ford 351W EFI-to-carb conversion swaps
- External-coil design supports 35,000V+ coils for more spark energy
- Machined aluminum housing with steel gear for durable timing control
Description
Convert your factory-EFI Ford 351 Windsor (351W) V8 to a carbureted ignition system with this Pro Series Ready-to-Run distributor, featuring an onboard ignition module and magnetic pickup trigger that eliminates the need for a separate ignition box, while the external-coil design keeps the flexibility to run a higher-output coil. This distributor supports 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 and a coil rated at 35,000 volts or higher; 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 a Ready-to-Run (RTR) EFI-to-Carb Conversion Distributor?
An RTR distributor has the ignition control module built directly into the housing, so it fires off a single 12-volt source without needing a separate ignition box wired into the circuit. Because this unit is also 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
Keeping the coil external allows the use of a higher-output coil than the 35,000-volt minimum, adding spark energy for the carbureted setup. The onboard ignition module holds timing steady without the wear and 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.

Engine Fitment
COMPATIBLE WITH
FORD SMALL BLOCK WINDSOR V8 (EFI-TO-CARB CONVERSION)
• 5.8 L / 351 in³ (351W)
NOTES
• Designed for Ford 351W EFI-to-carburetor conversion applications only.
• Due to the longer gear/shaft configuration, it is not intended for engines that came carbureted from the factory — carbureted 351W engines (1969–1987) require a different distributor.
• Will not fit 351C (Cleveland) or 351M (Modified) engines — those are a different engine family.
• Will not fit any other Windsor displacements (221, 260, 289, 302).
• The 351W was fully EFI from 1988 onward; all EFI 351W applications are compatible with this distributor when converting to carburetor.
• Requires an external coil with a minimum output of 35,000V — no separate ignition box required.
• Requires a 12-volt electrical system with alternator.
• Distributor gear is most compatible with cast iron hydraulic or solid flat tappet camshafts; consult camshaft manufacturer for recommended gear material before installation.
COMMON VEHICLE APPLICATIONS
Ford F-Series (5.8L, 1988–1996)
Ford Bronco (5.8L, 1988–1996)
Ford E-Series / Econoline (5.8L, 1988–1996)
Ford F-150 Lightning (5.8L GT40, 1993–1995)
Ford Mustang Cobra R (5.8L, 1995)
Q&A
What's the difference between this and the standard 351W Ready-to-Run distributor?
This version is designed specifically for EFI-to-carburetor conversions and uses a longer distributor shaft and gear than the standard carbureted 351W Ready-to-Run 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 a separate ignition box with this distributor?
No. The ignition control module is built into the distributor housing, so no external ignition box or CDI unit is required.
Does this distributor include a coil?
No. This is an external-coil Ready-to-Run distributor and requires an ignition coil rated at 35,000 volts or higher, which is sold separately.
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.
Emissions Notice
This Top Street Performance (TSP) product is designed for racing and off-road competition use only. It is not legal for use on public roads or emissions-controlled vehicles and does not comply with federal, state, or local emissions regulations. The buyer assumes all responsibility for legal use and installation.
What is a Emissions-Controlled Vehicle?
"An emissions-controlled vehicle is any vehicle equipped with a factory-installed emissions control system designed to reduce air pollution. These systems include catalytic converters, oxygen sensors, EGR (Exhaust Gas Recirculation) valves, and diesel particulate filters (DPF). Most vehicles manufactured after 1975 are considered emissions-controlled and must comply with federal and state emissions laws when used on public roads."
