can a mechanic tell if an engine is good or bad by just looking at it?

I'm replacing the engine in my car and the mechanic I'm using is not sure if the new engine is good or not. Can a good mechanic actually tell the difference between a functional engine and a bad one by doing a thorough examination of the engine?

    If he can see and hear it running, yes. Other than that, it's just a "boat anchor"
