Ford Small Block '88-'91 Truck & Van 5.8 L V8 EFI Distributor

• Hall-effect trigger for computer-controlled ignition accuracy

• Distributor-mounted module — direct replacement for factory setup

• Fits 1988–1991 F-150/F-250/F-350, Bronco, E-Series 5.8L/351W

• Machined aluminum housing with steel gear for durable timing control

Replace your 1988–1991 Ford 5.8L/351W truck or van's factory EFI distributor with this TSP Hall-effect distributor, built for computer-controlled ignition systems with a distributor-mounted module — matching the factory configuration used on Bronco, E-150/E-250/E-350, and F-150/F-250/F-350 applications from these years. Because timing is managed by the vehicle's computer, this distributor is matched to the factory-style advance curve rather than a mechanical or vacuum advance mechanism.

This distributor is built specifically for computer-controlled 5.8L/351W truck and van applications with a distributor-mounted module and is not designed for car applications. The housing is aluminum with a steel drive gear best matched to cast iron hydraulic or solid flat-tappet camshafts, and rotation is counterclockwise. Requires a coil matched to the vehicle's factory computer-controlled system, along with a 12-volt electrical system with an alternator.

What Is a Computer-Controlled EFI Distributor?
Unlike an EFI-to-carb conversion distributor, this unit is designed to work with the vehicle's factory computer-controlled ignition system rather than replace it. A Hall-effect trigger sends timing signal to a distributor-mounted ignition module, which manages the advance curve electronically instead of relying on mechanical or vacuum advance — matching how these 1988–1991 trucks and vans were originally engineered to run.

Performance Benefits
The Hall-effect trigger provides a clean, consistent signal to the factory-style distributor-mounted module, supporting reliable timing accuracy without the wear-related drift of an aging factory distributor. Because this distributor is purpose-built for the specific 1988–1991 5.8L/351W computer-controlled truck and van platform, it's matched to the factory-style ignition behavior these vehicles were designed around.

What vehicles and years does this distributor fit?
This distributor fits 1988–1991 Ford Bronco, E-150, E-250, E-350, F-150, F-250, and F-350 models equipped with the 5.8L (351 Windsor) computer-controlled EFI V8 engine and a distributor-mounted ignition module.

What's the difference between this and TSP's 1990–1997 351W EFI distributor?
This version is designed for the distributor-mounted ignition module used through the 1991 model year. TSP's 1990–1997 distributor is intended for later applications that use a different ignition module configuration. If your vehicle falls within the 1990–1991 overlap years, verify which ignition module style your engine uses before ordering.

Is this a carbureted distributor?
No. This is a computer-controlled EFI distributor designed to work with the factory electronic ignition system. It is not compatible with carbureted engines or EFI-to-carburetor conversions.

Does this distributor include a coil or ignition module?
The distributor is designed for the factory-style distributor-mounted ignition module configuration. The ignition coil is external and is not included. Use a coil compatible with your factory EFI ignition system.

Will this fit a car with a 351W, not a truck or van?
No. This distributor is designed specifically for the 1988–1991 Ford truck and van EFI applications listed. It is not intended for passenger car 351 Windsor applications.

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