A "030 over" 400 engine refers to a 400 cubic inch engine that has been bored 0.030 inches over its stock bore size. The stock bore size for a Chevrolet 400 engine is 4.125 inches, so boring it 0.030 inches increases the bore size to 4.155 inches. This modification can enhance performance by allowing for larger displacement and increased airflow.
