Ok then, it came from a stolen boat. Either way it's been deliberately tampered with in a deceitful way and it's a giant red flag to law enforcement. With all the parts that you sell and deal, surely you have run across blocks with butchered pads like this. It's no big secret that high-horse cars were OFTEN snatched up for their motors. I've seen many, many blocks just like this. No matter how long ago it happened, some over zealous State Inspector or Highway Patrol will see that suspicious pad in whatever car it ends up in, seize the vehicle and then they will disassemble it for the owner by removing the heater box, cutting a nice little square hole in the floorboard to read VIN stamping on the frame, check transmission VIN, etc. This IS exactly what happens and I would be wary of having that block in my possession with the way that pad currently looks.
