The S&S Cycle Power Pack for M8 models with part number 310-1399A offers an upgraded performance solution designed to enhance your motorcycle's power and reliability. Featuring an updated profile to fit M8 engines, including VVT models, this kit is engineered for seamless integration without the need for case machining. The big bore bolt-on kit increases engine displacement from 107 inches to 129 inches, delivering significant power gains while maintaining the original engine height for compatibility and ease of installation. Constructed with high-quality components, the system includes an S&S oil pump and cam plate, along with removable passage plugs for convenient servicing. Independent scavenge sections for the flywheel cavity and cam chest improve oil flow and cleanliness, aided by debris screens in both scavenge pickups and a magnet in the cam chest to prevent debris from entering the oil pump. The oil flow capacity is increased on both feed and scavenge sides, ensuring efficient lubrication during high-performance operation. An adjustable pressure relief valve allows fine-tuning of oil pressure with the unit installed, providing flexibility for different riding conditions. The kit features Quickee pushrods with pushrod tubes and S&S premium tappets, all coated with black hard anodized, billet aluminum tappet cuffs for durability. S&S valve springs are compatible with cams up to 0.605 inches lift, utilizing a high-performance conical single wire spring design to optimize valve operation. The inclusion of a multi-layered steel (MLS) head gasket ensures a reliable seal under increased pressure. The 496 camshaft enhances power delivery across the rpm range. Designed and manufactured in the USA, this Power Pack retains stock engine height, works with stock crankcases, and is compatible with both stock and S&S roller rocker arms. The design preserves original engine serial numbers and works with both first-generation round port and second-generation oval port stock valve springs, making it a versatile upgrade for your Harley-Davidson M8 engine. Whether you seek increased horsepower, improved oil management, or a reliable high-performance upgrade, this S&S Cycle Power Pack provides a comprehensive solution for your motorcycle’s needs.
