On my '96 525SC, I couldn't find the number either until I tore it apart. There was no riveted tag, but the engine was still wire sealed on the intake and crank pulley bolts.
I finally found it when I rebuilt the top end. The serial was stamped into the block behind the fuel filter seapump bracket, just below the cylinder head, if I remember correctly. Also the stamping was only about the same size as the type you are reading now.
