What is the spark plug gap of a 75 ford f-100?

The spark plug gap for a 1975 Ford F-100 depends entirely on the engine it has. Ford F-100s in 1975 came with a variety of engines (inline 6s, V8s of different displacements). The recommended gap is specified in your owner's manual or a repair manual specific to your truck's engine.

You cannot determine the correct gap without knowing the engine size and type. To find the correct gap:

1. Locate your engine's specifications: Look for a sticker under the hood or in the glove compartment that indicates the engine type (e.g., 302 cubic inch V8, 390 cubic inch V8, 240 cubic inch inline 6).

2. Consult a repair manual: A Haynes or Chilton manual for your specific year and engine will give the correct spark plug gap.

3. Check online resources: Websites like Ford's owner's manual website (if available) or automotive repair forums may provide this information if you know your engine type.

Without this information, providing a gap is impossible and could potentially damage your engine.
