Question: Are you wanting a turn-key engine or a project?
Find a AAZ block, and I have a complete engine that had a crack on the exhaust side of the block, midway. The welder couldn't fix it, so I used commercial Enecon forming metal and made the repair. The repair probably will hold. Enecon is tuff stuff. Still on my engine stand.
This engine ran perfect, cranked and ran good, and used no oil. I installed in my Caddy at 88K and developed the coolant leak and pulled at 103K.
Its taking up space, I am going to sell it or part it.
