Power Package - Oil Cooled - 496 Chain Drive - Wrinkle Black w/Highlight - M8
The S&S Cycle Power Package for M8 models, part number 310-1390A, offers a comprehensive upgrade for your Harley-Davidson touring motorcycle. Designed to fit M8 models including the VVT variants, this kit features an updated profile that ensures optimal performance without requiring case modifications. The big bore bolt-on kit increases engine displacement from 114 or 117 cubic inches with a 4.50-inch stroke to 132 cubic inches, delivering significant power gains. Constructed with high-quality components like an S&S oil pump and cam plate, the system ensures reliable lubrication and efficient oil flow throughout the engine. Passage plugs are removable for easy servicing, and independent scavenge sections for the flywheel cavity and cam chest help maintain oil cleanliness and engine longevity. A debris screen in both scavenge pickups and a magnet in the cam chest work together to prevent debris from entering the oil pump, protecting vital engine components. The increased oil capacity on both feed and scavenge sides promotes better lubrication under demanding conditions. An adjustable pressure relief valve allows fine-tuning of oil pressure with the unit installed, providing customization for various riding styles. The package includes quickee pushrods with pushrod tubes, premium S&S tappets, and hard anodized, black-coated tappet cuffs made from billet aluminum for durability. S&S valve springs are compatible with cam lifts up to 0.605 inches, featuring a high-performance conical wire spring design for added stability. The 496 cam is engineered specifically for big bore applications, enhancing power output. Multi-layered steel (MLS) head gaskets ensure a reliable seal, and the entire kit is made in the USA. It retains the stock engine height and works seamlessly with stock crankcases, as well as the stock and S&S roller rocker arms. The design preserves original engine serial numbers and is compatible with both first-generation round port and second-generation oval port valve springs, making it a versatile upgrade for your Harley-Davidson engine. This power package provides a substantial boost in horsepower and torque while maintaining the factory look and feel, ideal for riders seeking performance enhancements without extensive modifications.
