Building massive power reliably just got easier! Our new MK-Series B Crankcases can be paired with our 136" cylinder kit and 4 5/8" Stroker Crank to give you a rock-solid build. These cases scrape more oil than the stock ones, have a large volume sump, and fit in a stock frame without modification.
