Dan, there are many cars that have the VIN stamped into the engine block, my Gran Sport is one of them, it has a "numbers matching" engine as it is the original with the same VIN that is stamped on the body being on the engine.
Of course these days it means a little less being there are so many fakes out there, I mean, it sure isn't that big of a deal to deck a block and then stamp the cars VIN that the motor will be put in, voilą matching numbers.
