Millhouse,
Dan is correct in these motors when run hard get damaged all the time. The heads crack and blocks get broken. Keep in mind drag racers do not care about that stuff. The crank might be cut a whole lot and chances are it has pop up pistons in it which are no good on the street. The other thing that comes to mind if the car rotted down what does the inside of the motor look like. If the man is so sure it is good he should let you tear it down. imho.
