Built for M8 models, including VVT versions, this bolt-on big bore kit takes compatible 114"/117" M8 engines with a 4.50" stroke to 132" without case machining.
It includes 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.
Also featured are increased oil-flow capacity on the feed and scavenge sides, an adjustable pressure relief valve that can be set with the unit installed, Quickee pushrods with pushrod tubes, S&S premium tappets, hard-anodized black coated tappet cuffs, and S&S valve springs designed for cams up to 0.605" lift.
The 496 cam is designed for big bore applications, and the kit uses an MLS head gasket. It retains stock engine height, works with stock crankcases, and is compatible with stock and S&S roller rocker arms. Original engine serial numbers are retained.
