Hey I have a Farmall MD and the previous owner who used it for pulling has passed away but he was the only one who knew what modifications were done to the tractor so out of curiosity I pulled the head off the Tractor and it looks as if the previous owner bored it out until he hit where the coolant/water should be then put a wet sleeve and piston from a different diesel in it (since nobody that I'm aware of made wet sleeves and pistons that big for an MD) is this possible? Also it roall's coal like crazy any time its under heavy load so there must be something done to the fuel system/injectors. Does anyone have a ballpark idea of how much horsepower this setup would make? and if I were to pull with this tractor is there a chance it would grenade the transmission from that extra power? Any information would be greatly appreciated.
