Description

These 4 1/4″  (107.95mm) bore kits are easy to install as no machining of the crankcase is required. Kits include forged pistons, piston rings, wrist pins, clips, cylinders in all wrinkle black or wrinkle black with highlighted fins, and head and base gaskets. 124CI (2,035cc) kits are for use in 107CI Milwaukee Eight engines with stock 4.375″ stroke. The 128CI (2,100cc) kits are for use in 114CI and 117CI Milwaukee Eight engines with stock 4.500″ stroke.

Note: OEM head bolts are a stretch-to-torque design and can only be used once. Consequently, installation requires the use of 8 new head bolts or a super strong and re-usable S&S or Feuling/ARP head bolt kit.
