Transform your engine with the 132" Power Package Engine Performance Kit — a bolt‑on big bore solution that increases displacement without case machining and retains stock engine height.

This complete kit features a 4.320" big bore cylinder with forged pistons and an HPT496 cam engineered for big bore applications, plus S&S premium tappets and hard anodized billet tappet cuffs for lasting durability.

Oiling upgrades include an S&S oil pump/cam plate, independent scavenge sections for the flywheel cavity and cam chest, debris screens in both pickups, and a magnet in the cam chest to help keep contaminants out of the oil pump.

Serviceability and performance items: removable passage plugs for servicing, increased oil flow capacity on feed and scavenge sides, an adjustable pressure relief valve adjustable while installed, Quickee pushrods with pushrod tubes, S&S valve springs compatible with cams up to 0.605" lift, and an MLS head gasket.

The kit is designed to work with stock crankcases and roller rocker arms, retains original engine serial numbers, includes a 132 cam cover badge, and is made in the USA.
