You will need an externally balanced flywheel (three big holes). The pilot hole in the crank shaft is not deep enough for the 833 input shaft. It is easy to just cut a 1/4 inch off of the input shaft with a cut off wheel (no dissassembly required). The drivers side motor mount is different also. How about the accessory drive? V belt or serpentine? Fuel pump, mechanical or electric? Fuel injection or carb?
