Two of the original spec numbers on this were 47651 & 47147C of which the 7752233 shortblock is the replacement. If you buy a complete engine, you will have to use the oil pan off of your original engine because it will have four threaded holes toward the middle of the pan that you will bolt up through. The K341 16hp will have a 1-1/4" exhaust port instead of the 1" port size of the original engine.
