  • The Dart Big M Sportsman block was designed to be a more affordable version of the highly popular Big M.
  • The Sportsman block is fitted with ductile iron 4-bolt main caps, and features a redesigned lubrication system that oils all of the main bearings before the lifters for extra reliability.
  • Dart added two slotted head stud bosses on both sides of the lifter valley so you can use studs instead of hard to install bolts to take the place of the "missing head bolts".
  • Thanks for looking!
  • SHIPPING TO A BUSINESS IN THE LOWER 48 STATES WITH MEANS TO UNLOAD IS FREE! ADD 34.00 RESIDENTIAL AND 84.00 LIFT GATE.
