Standard Ignition FD-320 Distributor Rotor

Distributor Rotor for Holley Applications

The Standard Ignition FD-320 distributor rotor is built for Ford vehicles using a Holley distributor. It uses a high-dielectric alkyd body to resist dirt buildup and reduce carbon tracking, while solid brass segments support strong conductivity and consistent spark delivery to the plugs.

Compatible With 1963-1967 Ford Bronco, F-100, F-250, F-350, Mustang, and Econoline applications equipped with a Holley distributor. This part cross-references Standard Ignition FD-320 for the same application.

Key Features

• High-grade dielectric alkyd construction helps resist dirt sticking and carbon tracking
• Solid brass segments improve conductivity for higher voltage spark transfer
• Shaft retention clips are used where required for fit and performance
• Distributor rotor for ignition distributor service
• Standard Ignition FD-320 replacement part number

Detailed Description

Standard Ignition FD-320 is a distributor rotor engineered for Ford ignition systems that use a Holley distributor. The rotor’s dielectric material helps maintain electrical isolation inside the distributor, while the brass contact segments support efficient spark routing from the coil to the correct plug terminal. For restorations, tune-ups, or ignition service on classic Ford trucks and cars, this rotor addresses wear at a critical point in the ignition path.

Fits 1966-1967 Ford Bronco, N/A; Fits 1963-1967 Ford F-100, N/A; Fits 1966-1967 Ford F-250, N/A; Fits 1966-1967 Ford F-350, N/A; Fits 1964-1967 Ford Mustang, N/A; Fits 1963-1966 Ford Econoline, N/A.

What It Helps Solve

• Weak or inconsistent spark delivery through the distributor
• Carbon tracking inside the distributor cap area
• Rotor wear that can affect ignition timing transfer
• Misfire concerns related to rotor contact degradation
• Service issues on Ford Bronco, Mustang, and truck ignition systems with Holley distributors

Installation Notes and Tips

Verify distributor style before installation; this rotor is specified for Holley distributor applications. Inspect the distributor cap, terminals, and shaft condition during service, and confirm the rotor seats correctly on the distributor shaft before reassembly. The FD-320 part number is a useful reference when matching the correct ignition rotor for classic Ford applications.

Quality Assurance

Standard Ignition uses materials and construction methods aimed at stable electrical performance and extended service life. The rotor design reflects long-running development in distributor cap and rotor engineering for dependable ignition service.
