About This Product
This S&S 128-inch Power Package is a chain-drive performance solution for oil-cooled 114 and 117-inch Milwaukee-Eight engines. By utilizing 4-1/4 inch bore cylinders and 11:1 forged pistons, this kit increases displacement without the need for engine case machining. The package includes a high-volume blue anodized billet oil pump and cam plate, featuring magnetic debris traps and independent scavenge sections. To optimize the power curve, S&S provides a 550 cam, conical valve springs, and Quickee pushrods with chrome covers. Billet aluminum tappet cuffs are also included to maintain valvetrain alignment under high-lift conditions. This American-made set is sold as a kit.
Manufacturer part number: 310-1109B.
