I would get rid of that block with the 666 in the number BAD OMEN from t he word go LMAO

engine Casting number is usually found at the rear of the block on the left or drivers side on top of the bellhousing flange.

The pic you show is more than likely the vin to car they partial stamp the vin on motor ............
