What is the spark plug gap for a small block Chevy 350 crate motor?

The recommended spark plug gap for a small-block Chevy 350 crate motor depends on the specific engine's specifications and the type of spark plugs used. There's no single universal answer.

You MUST consult your engine's specific documentation. This information will be in the owner's manual or on a sticker affixed to the engine itself. The documentation will specify the correct gap for the recommended spark plugs.

Generally, a gap between 0.035" and 0.045" is common for small-block Chevy 350s, but again, this is a *general range* and not a guaranteed value. Using the wrong gap can lead to misfires, poor performance, or engine damage.
