Upgrade your Harley-Davidson M8 engine with the S&S Cycle 132" Power Package, part number 310-1400. Designed for 114" and 117" models with 4.50" stroke, this kit boosts engine displacement from 114"/117" to 132" without the need for case machining. The kit features a big bore 4.320" cylinder, paired with 11.0:1 forged pistons, delivering increased power and performance. The package includes an S&S oil pump and cam plate, with passage plugs that are removable for easy servicing, and independent scavenge sections for the flywheel cavity and cam chest to ensure optimal oil flow. A debris screen in both scavenging pickups and a magnet in the cam chest help prevent debris from entering the oil pump, enhancing engine longevity. The oil flow capacity is increased on both feed and scavenge sides, promoting efficient lubrication under demanding conditions. An adjustable pressure relief valve allows fine-tuning of oil pressure while the engine is in operation. The kit comes with quickee pushrods, S&S premium tappets, and hard anodized, black-coated tappet cuffs made from billet aluminum for durability. S&S valve springs are included, suitable for cams up to 0.605" lift, featuring a high-performance conical single wire design for reliable valve operation. The HPT496 cam, specifically designed for big bore applications, delivers impressive performance gains. Multi-layered steel (MLS) head gaskets are included to ensure a perfect seal. The package also includes a 132" cam cover badge and retains stock engine height, making it compatible with stock crankcases, valve springs (both first and second-generation styles), and roller rocker arms. Made in the USA, this comprehensive upgrade maintains original engine serial numbers and is an ideal choice for enthusiasts seeking substantial power increases with a professional-level installation.
