Looks suspiciously like marine/ reverse rotation to me, what say you?

So I guess someone could use it as a nice block and crank on an early build B body? Are the motor mounts the same? It's not not like it would be numbers matching but if it is new that is a deal.

For me that much for a block and crank and maybe rods is a lot of money Interesting, the add has been deleted!!!
