Why couldn't a large-journal cam have the bearing areas ground to the smaller diameter? If a cam grinding machine isn't capable of doing that, surely a little creative setup on a crankshaft grinder would get the job done. Making stuff smaller is easy! I'll bet I could do that on a good lathe with a tool post grinder.
