Just in case (no pun intended) it's not listed here already, there's a 914-6 engine block for sale on the 911S registry

Long shot, but someone may be looking for this case to match a chassis VIN

901/36 motors are euro spec, so is the engine number. Most likely doesn't belong to a North American 914-6. Could be a real find at the price though.
