Spark plug gap for 1976 Chevy Cheyenne pick up?

The spark plug gap for a 1976 Chevy Cheyenne pickup depends entirely on the engine it has. Cheyenne pickups from that year could have a variety of V6 and V8 engines. You must consult your owner's manual or a repair manual specific to your truck's engine to find the correct gap.

Without knowing the engine size and type (e.g., 350 small-block V8, 400 small-block V8, 305 V8, 250 inline-6, etc.), it's impossible to give you the correct information. The gap can vary from around 0.035 inches to 0.050 inches depending on the engine. Using the incorrect gap will negatively affect performance and can damage your engine.
