The foundation for our engine build is Dart's Big M iron cylinder block that is a beefier replica of the Mark IV-style Chevy big-block casting. It is designed with the standard camshaft height and accepts almost all conventional big-block parts. It is also available in a variety of cylinder-bore and deck-height configurations. Ours uses a standard 9.800-inch deck height. Other unique features include true priority main oiling, a stepped mail oil gallery that delivers more oil to the crankshaft at higher rpm. The block weighs 260 pounds.
