For someone who wants to do an original restoration, that running shape 216 would probably be pretty much in demand. Just be sure not to let it deteriorate in storage. Here's a sneaky trick- - - -drain as much oil as possible from the crankcase, and fabricate some sort of cradle so it can be stored upside down. The residual oil will pool around the pistons, rings, valves, etc., and prevent them from rusting and/or sticking the rings and valve guides. Removing the intake/exhaust assembly and bolting a piece of wood over the ports will help, too.
