The 212/225/115 is the 068 cam. I think the RA III cam is the 744 at 224/236 on 115.5 LSA. If down the road, someone wants an original, then a non stock cam will not do. That being stated, if the engine requires boring, new bearings, new pistons, then it will no longer be 'original'. Of course the engine will have to be disassembled to verify. Most likely just numbers matching will do.
