  • The 97in. Big Bore kit for 88in. motors yields excellent results with stock cylinder heads
  • Feature the largest bore (3.927in.) that can safely be used in a cylinder with stock spigot diameter
  • Even though stock cylinders can be bored to fit the 3.927in. pistons, the included S&S cylinders feature a much stronger cast iron liner to stand up to the added power

  • Specifications: 3.927in. bore, 4in. stroke, 97in. displacement, 9.7:1 compression ratio with stock heads (9.3:1 compression ratio with S&S 89cc heads or 10.7:1 with S&S 79cc heads)
  • Kits include cylinders, pistons, rings and gaskets (head, base and exhaust)
  • Black or silver powder-coat finish
  • Made in the USA
  • This project requires a skilled technician. It is the responsibility of the person assembling the parts to check all clearances and assembly specifications.
