I am wondering if A/C did engine swaps in the factory?? My 312D has a k341S-16hp confirmed by measuring the bore-3.75 in. The reason I ask is beecasue the engine looks pretty beat to be a repower, I looks ~40 yeas old Is this normal??

That is definitely a newer engine. At some point later in the production of the 341's they changed the number of cooling fins and the shape of the cylinder head, but I'm not sure if it was increased or decreased, but yours is definitley newer than '75. If you can make out the serial # of the engine, the service manual will give the date range in which the engine was built.
