About This Product
The S&S 129-inch Power Package offers a gear-drive performance upgrade for 107-inch oil-cooled Milwaukee-Eight engines. This kit features a 550G camshaft and big bore cylinders that increase displacement without requiring engine case modifications. The package includes a high-flow oil pump and cam plate assembly, designed with independent scavenge sections to optimize oiling. For a custom look, this version includes Quickee pushrods with gloss black covers. The kit is rounded out with hydraulic tappets, billet tappet cuffs, and MLS head gaskets to ensure a reliable seal. Manufactured in the U.S.A. by S&S Cycle, this comprehensive engine performance solution is sold as a kit.
Manufacturer part number: 310-1228.
