Unleash the full potential of your Harley-Davidson M8 engine with the S&S Cycle Power Pack VVT Engine Performance Kit. Engineered for 107" M8 models, this comprehensive kit dramatically increases displacement to 129" without requiring any case machining, making it a true bolt-on big bore upgrade.

Description

The S&S Cycle Power Pack VVT Engine Performance Kit is meticulously designed to transform your M8 into a high-performance powerhouse. Featuring an updated profile to perfectly fit all M8 models, including those with VVT, this kit delivers a significant boost in torque and horsepower. At its core is a state-of-the-art S&S oil pump and cam plate system, boasting independent scavenge sections for both the flywheel cavity and cam chest, ensuring optimal oil management. Enhanced oil flow capacity on both the feed and scavenge sides, coupled with removable passage plugs for easy servicing, guarantees long-term reliability. A strategically placed magnet in the cam chest and debris screens in both scavenge pickups actively prevent contaminants from entering the oil pump, safeguarding your engine's vital components. The adjustable pressure relief valve can even be fine-tuned while the unit is installed in the engine, offering unparalleled flexibility.

Beyond the advanced oiling system, this Harley-Davidson M8 big bore kit includes S&S Quickee pushrods with pushrod tubes and premium S&S tappets, complemented by billet aluminum, hard anodized black coated tappet cuffs for superior durability. High-performance conical single wire S&S valve springs are included, capable of handling cams up to 0.605" lift, ensuring a robust valvetrain. The kit is rounded out with an MLS (multi-layered steel) head gasket and a powerful 496 camshaft, all contributing to exceptional performance. Proudly Made in the USA, this S&S VVT engine upgrade retains stock engine height and works seamlessly with stock crankcases, as well as both stock and S&S roller rocker arms, preserving your original engine serial numbers.
