The 5EK and 6TS engines are basically the same with only the early 5EK being different in the lowest Hp ratings. I can't remember where the serial number break is in the 5EK when they went to steel piston crowns regardless of the Hp rating, but this is when the 5EK and 6TS is the same engine. Any 5EK built with a higher Hp rating than 435 when it left the factory is the same regardless of the serial number as a 6TS with the same power rating
