I doubt the engine is original. The stamping looks suspect and it is a 388 block. I have never seen a 388 block that was built at Flint engine. The 388 block was used at Tonawanda. This car should have a 618 block, I think it's a little too late for the 386 block. There are a few things that keep this car for being a $50K plus car, but it is still a nice Z28.
