Other than the broken exhaust manifold, everything is in pretty good shape. The bottom end (crankshaft and connecting rods)  are all chrome plated. The crank is actually cut into two sections and machined down on both ends to ride smoothly on sealed roller bearings. The flywheel attaches to the remaining section of the crank. The camshaft is also installed with roller bearings, however the rod bearings are actually thin Teflon strips with thin brass ships for a tight fit. After complete teardown, all components are headed for a good washing.
