Transform an early Harley-Davidson Twin Cam engine with the S&S Cycle 330-0665 100-Inch Power Package. Designed to increase displacement from 88 cubic inches to 100 cubic inches, this comprehensive performance kit combines a 4-inch-bore bolt-on cylinder and piston assembly with matched cam chest components for dependable high-performance power. The kit features a 10.5:1 compression ratio and a durable wrinkle-black finish for a clean, purposeful appearance.
S&S Cycle includes 585 Easy Start chain-drive cams, a TC3 oil pump, TC3 cam plate, cam chain tensioners, Quickee adjustable pushrods with tubes, and S&S precision tappets. The cylinders are fit to the pistons, eliminating the need for additional machining, while the low-friction ductile cast-iron liners support durability and efficient operation. This package is designed to bolt in without machining, balancing, or splitting the crankcases, making it a practical upgrade for compatible Twin Cam 88 applications.
The S&S Cycle 330-0665 Power Package includes the components needed to upgrade the cam chest and engine displacement in one convenient part number. It is not compatible with S&S 79cc Super Stock heads and is not recommended for Tri-Glide or other three-wheel models because of the lugging characteristics of these motorcycles. Although an oil cooler is not mandatory, S&S Cycle recommends one for motorcycles operated in warmer climates. This product is not CARB approved, and applicable emissions requirements should be verified before installation or use.
Fitment includes select 2001 Harley-Davidson Softail models, including the FLSTFI Fat Boy, FXSTBI Night Train, FXSTDI Softail Deuce, FXSTI Softail Standard, and FXSTSI Springer Softail, along with select 2002 Touring and Softail models such as the FLHRCI Road King Classic, FLHTCI Electra Glide Classic, FLHTCUI Electra Glide Ultra Classic, and FLSTCI Heritage Softail Classic. Verify exact motorcycle compatibility before ordering.
