Built as a bolt-on big bore upgrade for M8 models, including VVT models, this 132" Power Package Performance Kit is designed to increase a 114"/117" with a 4.50" stroke M8 to 132" without case machining.
It uses an S&S oil pump/cam plate with removable passage plugs for service, independent scavenge sections for the flywheel cavity and cam chest, debris screens in both scavenge pickups, and a cam chest magnet to help keep debris out of the oil pump.
You also get increased oil flow capacity on both feed and scavenge sides, an adjustable pressure relief valve that can be adjusted with the unit installed, Quickee pushrods with pushrod tubes, S&S premium tappets, and S&S hard anodized black coated tappet cuffs with billet aluminum construction.
The package includes S&S valve springs that work with cams up to 0.605" lift, a 496 cam designed for big bore applications, and an MLS head gasket. It works with stock crankcases, retains stock engine height and original engine serial numbers, and is compatible with the stock and S&S roller rocker arms. Made in the USA.
