John, According to the Continental Service Bulletin M47-16 dated 12-30-47, major internal parts were changed including the crankshaft, piston and rod assemblies, valve seats etc etc. After the new parts were installed and carb and mags changes etc. specified by Continental were made, the original engine ID plate and a 337 signed by a FAA inspector had to be sent in to Continental. They then issued a new engine ID plate with the new model number and with the old serial number followed by "C". If your engine still has the original ID plate, I would doubt that it was ever converted.
