What is the spark plug gap on a Chevy 350 small block?

The recommended spark plug gap for a Chevy 350 small block engine depends on several factors, including the year of manufacture, the specific application (e.g., stock, modified), and the type of spark plug being used. There's no single definitive answer.

However, a common and generally safe range is between 0.035" and 0.045". Always check your owner's manual or consult a reputable service manual for the precise specification recommended for your particular engine. Using the wrong gap can lead to misfires and poor engine performance.
