When choosing spark plugs for this engine, it is important to make sure they are designed to handle the power of the engine.
Spark Plug Type
The type of spark plug you will need depends on the type of performance you are looking for.

Heat Range & Gap
When selecting spark plugs for a 400 small block Chevy engine, it is important to choose the correct heat range and gap size. The heat range refers to how hot or cold the plug burns during operation. The gap size determines how much voltage can flow across the gap when the spark occurs.

In conclusion, the best spark plugs for a 400 small block Chevy depend on the desired results. For improved performance and fuel efficiency, a colder set of spark plugs is recommended.
