There is a 745TD in my garage right now with a shortblock that turns over freely. It sat in a dank garage for years w/ no head, so the bores are rusty, will need bored at least .5mm. It spun a belt, so crashed the valves. But it is a block, crank, rods. I'm swapping in a used engine from a 760 auto, so will be keeping the flywheel, and all the spare parts, like IP, turbo, oil pump, cooler etc.
I expect to get the old shortblock out in the next few weeks. You can have it in exchange for some good root beer (there are several good varieties at Trader Joes).
