Description

Experience a dramatic increase in horsepower and torque with this meticulously crafted M8 big bore kit. The S&S Cycle 132" Power Package features robust 4.32" bore cylinders paired with 11.0:1 compression ratio forged pistons, designed for extreme durability and performance. At its heart is the advanced S&S oil pump/cam plate, sporting a striking blue anodized finish. This system boasts independent scavenge sections for both the flywheel cavity and cam chest, ensuring optimal oil evacuation and lubrication. Thoughtful additions like debris screens in both scavenge pickups and a cam chest magnet actively prevent harmful particles from entering the oil pump, extending engine life. The increased oil flow capacity on both the feed and scavenge sides, coupled with an adjustable pressure relief valve, guarantees consistent oil pressure under all operating conditions. Installation is streamlined with Quickee pushrods, S&S premium tappets, and billet aluminum hard-anodized, black coated tappet cuffs. The kit includes high-performance S&S 550 cams, specifically designed for big bore applications, and S&S valve springs compatible with cams up to 0.605" lift, featuring a conical single wire spring design. Essential gaskets, including exhaust, cylinder base, and head gaskets, are provided for a complete installation. Proudly Made in the USA, this Harley-Davidson Milwaukee-Eight engine upgrade is built for serious enthusiasts seeking uncompromised power.
