318 in a 67 Notch???
Also, "numbers matching" is meaningless when you are talking about a 67 -- there are no numbers that match. So the guy doesn't know what he is talking about, to start with. I would bet it's a 273-2bbl and he just doesn't know the difference. People see my car all the time and the first thing they ask is "is it a 318?"... umm, no.
