132" Power Pack - 550 Gear Drive - Water Cooled - Black Granite w/Highlight Fins - 114"/117" M8
Upgrade your Harley-Davidson M8 engine with the S&S Cycle 132" Power Pack, part number 310-1236C, designed for high-performance big-bore applications. This bolt-in kit seamlessly increases your engine capacity from 114"/117" to 132" without the need for case machining, making installation straightforward and efficient. The kit features 4.32" bore cylinders paired with forged pistons that provide an 11.0:1 compression ratio, delivering enhanced power and torque. Additionally, the included components such as the S&S oil pump and cam plate, finished in a durable blue anodized coating, ensure reliable oil circulation and performance under demanding conditions. Passage plugs are removable for easy servicing, and the independent scavenge sections optimize oil flow from both the flywheel cavity and cam chest. A debris screen in each scavenge pickup helps prevent contaminants from entering the oil system, while the integrated magnet in the cam chest further guards against debris entering the oil pump. The kit also boasts increased oil flow capacity on both feed and scavenge sides, ensuring optimal lubrication during high-performance operation. An adjustable pressure relief valve allows fine-tuning of oil pressure without removing the unit from the engine. The package includes Quickee pushrods, S&S premium tappets, and hard-anodized, black-coated tappet cuffs made from billet aluminum for durability. The S&S 550 cams, purpose-built for big bore setups, are compatible with valve springs that handle lifts up to 0.605", utilizing a high-performance conical single wire spring design for reliability. All necessary gaskets, bearings, and hardware are included for a bolt-on installation, ensuring a complete upgrade. Made in the USA, this power pack is a robust choice for enthusiasts seeking increased horsepower, torque, and overall engine performance, excluding applications for 121" CVO models.
