Product Details

Features

  • Internal 65,000V coil delivers stronger spark for inline-six ignition
  • One-wire hookup — no external coil or ignition box required
  • Direct fit for Ford 240/300 Big Six inline-6 carbureted engines
  • Machined aluminum housing with included vacuum advance tool

Description

Upgrade your Ford 240 or 300 Big Six inline-6 ignition system with this HEI-style distributor, built around a magnetic trigger and a 65,000-volt coil housed directly in the distributor — 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 industrial 240/300 applications.

The housing is machined aluminum with a steel drive gear, and the distributor uses a combined mechanical/vacuum advance tuned for carbureted street and performance use. 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 Distributor?
HEI (High Energy Ignition) replaces the external coil and breaker points used in factory Ford inline-six ignition systems with a magnetic trigger and a high-output coil built directly into the distributor housing. Without points to wear or require periodic gap adjustment, timing holds more consistently, and this single unit replaces both the original distributor and ignition coil.

Performance Benefits
The 65,000-volt internal coil produces stronger spark output than a factory points-style distributor, supporting more consistent spark delivery across the RPM range on the 240/300 inline-six. The magnetic trigger holds timing accurately without the point wear and drift common to older ignition systems. Mechanical and vacuum advance are both included, with a vacuum advance adjustment tool in the box so the timing curve can be tuned for the specific engine and application.

NOTES
• Designed for carbureted Ford 240 and 300 inline-six applications.
• The 240 was produced from 1965–1976; the 300 was produced from 1965–1986 in carbureted form (fuel injected from 1987 onward).
• Not compatible with Ford's earlier inline-six engines (144, 170, 200, 223, 250) — those require a different distributor.
• This distributor is designed for a 12 volt electrical system with an alternator.
• It is not compatible with a generator and cannot be used with a ballast resistor.
• 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 (240/300, 1965–1986)
Ford Bronco (300, 1966–1986)
Ford E-Series / Econoline (240/300, 1965–1986)

Q&A

Do I need an external ignition box with this distributor?
No. This HEI 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.

Will this work on a Ford 240 or 300 with a generator or ballast resistor still in place?
No. This distributor requires a 12-volt electrical system with a charging alternator. It is not compatible with generator-equipped vehicles or ballast resistor ignition circuits.

What direction does the rotor turn on this distributor?
Clockwise, matching the standard rotation direction used by the Ford 240 and 300 CID inline-six engine family.

Does this fit industrial or stationary 240/300 engine applications, not just trucks?
Yes. This distributor fits Ford 240 and 300 CID inline-six engines used in F-Series trucks, Bronco, E-Series vans, and compatible industrial and stationary engine applications.

Does this distributor include a coil?
Yes. This HEI distributor features an integrated 65,000-volt ignition coil built into the distributor cap. No external coil is required.

What type of advance system does this distributor use?
This distributor uses both mechanical (centrifugal) advance and vacuum advance. A vacuum advance adjustment tool is included, allowing you to fine-tune the ignition timing curve for your specific application.

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."
