Car ingested water & hydrolocked. Drained most of the water from the block. I am now able to rotate the crank pulley, but crank pulley will not rotate a full 360 degrees, something is obviously broken/bent internally. Would love to take it to a guru / specialist who has wet dreams of rebuilding BMW engines. Preferably in the South East but willing to deliver/ship the car for it to be in the right hands...
The second part to my question is do you think a standard 750 motor from 2013 and up will work rather easily as a replacement engine? If it does not makes sense to rebuild my original engine, I would wait for a wrecked Alpina engine to show up for sale somewhere... In the meantime, I would be happy with the standard 750 engine in order to get the car back on the road. I'm thinking it would work since the engines are so similar and its mostly the internals that are different. Obviously the engine management would be the tricky part, or maybe not?
Any help/thoughts are appreciated.... thank you. If there are any BMW Techs or Service Advisors reading this, please message me.

I wander what did you end up doing with your engine?
Technically, 750 f01 engine will bolt on with its original turbos. Alpina turbos are bigger. Also engine management and tranny management will have to be reprogrammed or all ecu's replaced, that's if you decide to go back to original engine.
I would probably rebuild that hydro-locked engine or get another same engine
