Engineered for applications where water between the bores is a requirement. Siamese bore versions are also available for larger bore applications. MRK IV blocks use the 2-piece rear seal design, and Gen V and Gen VI blocks use a 1-piece rear seal as well as a different timing cover pattern. These blocks are based on Dart's Big M2 design, and include features like priority main oiling and 4-bolt main caps.


In 1981, Dart Machinery began in a two-car garage in Oak Park, Michigan. In the years since, Dart has become the proven leader in aftermarket cylinder heads, intake manifolds and engine blocks.
