I met a guy some years back that bought a 645 I believe, at an auction for a give away price. The machine was smoking blue really bad and had oil pouring out somewhere running down the block. He told me the fix was very simple. Apparently a seal was gone, likely in the fuel pump allowing the crankcase to fill up with diesel fuel and spitting out excess wherever possible. This would make for very low oil pressure etc. This could be how the engine went downhill in the machine you're looking at. You could check if there is diesel present in the engine oil. The engine may not knock with a fresh oil change providing it hasn't been run too long this way.
The 745 is a very good machine and very powerful if the hydraulic pumps are good and transmission with converter put out proper pressures. It should weigh around 38000 lbs. I saw one 745 with a Detroit 6V71 installed. I don't think the retrofit is too hard for a good mechanic. The only accessory drive on the engine itself is the air compressor and that's an easy one for a Detroit. It may be just as easy to fit an inline 671 in there as well. They are so cheap and easy to be found.
