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

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.

COMPATIBLE WITH
FORD SMALL BLOCK WINDSOR V8 (EFI)
• 5.8 L / 351 in³ (351W)

NOTES
• Designed as a replacement distributor for factory EFI computer-controlled ignition systems — this is not a carbureted or EFI-to-carb conversion distributor.
• Fits 1988–1991 applications equipped with a distributor-mounted ignition module — not compatible with later remote-mounted module applications.
• Uses a Hall Effect trigger and computer-controlled advance — timing is managed by the factory EEC computer, not mechanical or vacuum advance.
• Must be used with the appropriate factory computer-controlled ignition system, external coil, and wiring harness.
• Will not fit car applications — truck and van fitment only.
• Will not fit 351C (Cleveland) or 351M (Modified) engines.
• Distributor gear is most compatible with cast iron hydraulic or solid flat tappet camshafts; consult camshaft manufacturer for recommended gear material before installation.
