The reason for asking is I have done a little research as to the specifications between the 730-830-930 tractors ,gas and diesel, and from what I can tell, it looks that their is a large number of parts that would interchange.Yes , the bore sizes are different,but in a sleeved motor, I would doubt the bore spacing is different,as it is far more efficent in the production of these parts by a manufacturer to keep as much in common as possible to lower costs.The parts catalogs list rod and main bearings for all thes tractors as the same PN.,gas and diesel, the 730 and 830 have the same crank stroke,and I believe are interchangeable. my gas tractor has the mounting provisions for a Injector pump ready to go...The only area I am unsure of ,is the outside diamiter of the sleeves. The other clue is the only AFTERMARKET overhaul kit(For a 251 gas) is avaliable with a 4 1/8 bore which is the same as the 267 ? diesel listed in the 730 tractor, and the overhaul kit for the 267 is 4 1/4 ,and that is the bore on the 830 diesel...you sorta see where I coming from now? It has been a pain to find a gas overhaul kit, but the diesels are falling out of the sky, can find one just about anywhere ... The only place I have found the gas kit is Ag Kits out of NY. Just trying to see if it made sense to spend a little more money, do the conversion and have a-lot more tractor when I'm done. Shawn
