unusual model H engine

Posted by sgt bull on January 04, 2006 at 09:42:16 from (65.73.245.237):

I have a 1940 model H with what appears to be a replacement engine. Engine has a dipstick, and the fuel pump boss had been ported and had tapped holes...now has a cover on it. I'm guessing it may have come from a combine, and could be the 153 engine instead of the 152. Can anyone advise what the compression should be? it's worn and all cylinders have about 55 lbs. Also, where does the extra inch displacement come from? would the 153 have the same bore and stroke as the 152, just a different head perhaps? They do appear to have different gasket kits. How can I determine for sure which engine I have? the only casting #s are on the rt side, consisting of stamping "6937" followed by cast letters "DF" above oil filter, "3.23.W" above distributor, and "6" below #4 spark plug. Local Case IH dealer was no help
