I am of the opinion that replacing the engine in a 782-2072 that has a blown engine is a way better move than spending money on a new plastic POS that is available today. I agree with Jon that they are probably not worth it as no body will give what they are worth when rebuilt but they are better than any thing you can buy today for the money you will have invested.
I just finished rebuilding a 1872 that includes a warranty take out 28 hp command EFI that I found for $1,100, I rebuilt the rear end and hydro, added a three spool hyd valve, front and rear hyd outlets, a three point hitch, New AG tires and a paint job. With the initial cost of the tractor I have around $3,500.00 invested in it and it is the nicest running and driving Cub Cadet I have ever drove. This tractor should last another 30 years if taken care of. What can you buy today for the same money that will last as long, and it is way better looking the stuff that you can buy today.
If it was me I would try to see why the 782 is overheating and correct it. Most likely adjusting the carb will cure it. I always run the hi speed fuel mix a little on the rich side to help with running hot. If and when you decide to upgrade to a CH engine having a good running opposed twin to sell would be a plus. Someone may have a use for it. Good luck
Tom
