Justin:

MB may have records on which serial number engine was installed in the car (believe it or not, you can actually get a copy of the original window sticker!).

Seriously, why flog a dead horse? I'd still just go down to the U-Pullit and grab an engine -- all you really need is a good block, and they are all the same up to the aluminum ones.
