looking for a A6, Z6, or Y7 engine or block

I'm looking for a D16Y7 engine, or at least the complete block minus the pistons and rods in good condition. Here are all the parts I'm after:
Y7 crank and crank timing gear
Y7, Z6, or A6 block
oil pump, pan, crank cradle and oil pickup; all matching the block

I'm trying to get a block that doesn't need bored and honed, if it's at all possible. One that isn't out-of-round or tapered, and hasn't been apart very long. Any parts would be a good help. Thanks
