Description
If you’ve already invested in performance upgrades for your big twin, the S&S Cycle T124 Series Engine lets you preserve those modifications while stepping up to 124 cubic inches of displacement. This long-block engine eliminates redundant fuel and ignition system costs—simply bolt your existing carburetor, throttle body, or tuner directly to the specially machined heads and ride. With forged pistons, high-flow internals, and a 10.8:1 compression ratio built for street performance, you get S&S reliability and power without starting from scratch.
