What is the spark plug gap for a small block Chevy?
Spark plugs for the Chevy 350 engine are readily available from any auto parts store. Spark plugs come pre-gapped, but you should always verify the gap with a spark plug gap tool. The gap for a 350 small block should be 0.035 inches.
What happens if your spark plug gap is too big?
The customer may experience loss of power, misfires, spark plug fouling, increased plug wear, or poor gas mileage. Too small of a gap may give too weak of a spark to complete the combustion process within the engine; too wide of a gap can lead to the spark plug not firing correctly, causing misfires at high speeds.
How do I know if my spark plug gap is wrong?
Select the correct measurement on your gap gauge or feeler gauge. If you can’t get the correct feeler gauge through the gap, the gap needs to be widened. If the tool runs through the gap without touching the electrodes, the gap is too big and must be narrowed. Use your spark plug gap tool to adjust the gap.

What does increasing spark plug gap do?
Most experienced tuners know that increasing the gap size increases the spark area exposed to the air-fuel mixture, which maximizes burn efficiency. For this reason, most racers add high-energy ignition systems. The added energy allows them to increase the gap, but still have enough voltage to jump the gap.
