Power Package - Water Cooled - 496 Gear Drive - Wrinkle Black w/Highlight - M8
Upgrade your Harley-Davidson M8 engine with the S&S Cycle Power Package part number 310-1403A, designed specifically for M8 models including VVT variants. This comprehensive kit increases engine displacement from 114-117 inches to an impressive 132 inches by utilizing a big bore bolt-on kit with a 4.50-inch stroke, requiring no case machining for installation. The package includes a high-performance camshaft, oil pump, cam plate, and related components engineered for optimal power and reliability. S&S’s advanced design features, such as removable passage plugs for easy servicing and independent scavenge sections for the flywheel cavity and cam chest, ensure efficient oil flow and maintenance access. The debris screen integrated into both scavenge pickups and the magnet in the cam chest work together to prevent debris from entering the oil pump, thereby enhancing engine longevity. The oil system boasts increased capacity for both feed and scavenging, ensuring superior lubrication under demanding conditions. An adjustable pressure relief valve allows fine-tuning of oil pressure with the unit installed in the engine, offering flexibility for different riding styles and engine setups. Quickee pushrods with pushrod tubes and S&S premium tappets provide reliable valve operation and durability. The hard anodized, black-coated tappet cuffs made from billet aluminum add a layer of wear resistance and aesthetic appeal. The S&S valve springs are compatible with cams up to 0.605 inches of lift and feature a high-performance conical single wire spring design, supporting high-lift cam profiles like the included 496 cam, optimized for big bore applications. The MLS (multi-layered steel) head gasket ensures a reliable seal, maintaining compression and preventing leaks. This power package is made in the USA, retains the stock engine height, and works seamlessly with stock crankcases, stock and S&S roller rocker arms, and both first and second-generation valve springs. Its design preserves original engine serial numbers and is compatible with various port types, providing a versatile upgrade for serious riders seeking increased horsepower and engine efficiency.
