A "400 small block bored over 30" refers to a 400 cubic inch small block Chevrolet engine that has been bored out by 0.030 inches. This modification increases the engine's displacement slightly, which can enhance performance by allowing for more air and fuel to enter the combustion chamber. The term "bored" indicates that the diameter of the engine's cylinders has been enlarged, which can lead to improved power output and efficiency.
