Upgrade your M8 engine with the S&S Cycle Power Pack, part number 310-1057C, designed to deliver increased performance and durability. This bolt-on kit features forged pistons and a 4.375-inch stroke, providing a significant boost in power output. The kit includes an oil pump and cam plate, both precision machined from billet aluminum, with removable passage plugs for easy servicing and maintenance. Its independent scavenge sections for the flywheel cavity and camchest, along with debris screens in both pickups, help ensure clean oil flow and reduce the risk of contaminants damaging your engine. Additionally, a magnet in the camchest captures debris before it can reach the oil pump, enhancing longevity and reliability. The oil supply flow is increased by 44%, and scavenge flow by 58%, promoting better lubrication and cooling under demanding conditions. The pressure relief valve is adjustable with the kit installed, allowing fine-tuning of oil pressure for optimal performance. The included Quickee pushrods are designed for quick installation and durability, while the hand-assembled tappets with close tolerances reduce valve train noise from startup to shutdown. The hard anodized black coating on the billet aluminum tappet cuffs provides extra wear resistance and stability during high lift and high RPM situations, ensuring consistent engine operation. This comprehensive Power Pack is made in the USA and offers a substantial upgrade for enthusiasts seeking enhanced performance, durability, and efficient oil management in their M8 engines.
