The bore in Sherman's Motown block will be 4.040 inches, and the SCAT crank will provide a 3.562-inch stroke. That's 365.2 ci, just under our displacement limit of 366. The SCAT crank is an Ultralite 4340 piece weighing only 43 pounds, and a steal for street guys at around $1,200. "These cranks come finished to the right sizes and work best for me with Clevite 77 or Vandervell bearings. I'll be using Clevite parts on this build. I really like these SCAT cranks. They are well engineered, affordable, and plenty strong."
