What is the spark plug gap for c3 corvette motor?

The spark plug gap for a C3 Corvette engine depends on the year and the specific engine it has (small block or big block, and even the year within those categories can affect it). There's no single answer.

To find the correct gap, you must consult your owner's manual or a reliable repair manual specific to your Corvette's year and engine. The information is usually found in the specifications section.

Failing that, a qualified mechanic will know the correct gap for your engine. Using the wrong gap can lead to misfires, poor performance, and damage to the engine.
