deward,
I would trust my numbers more than a person that is trying to sell something. However, he may truly believe that he purchased it with a 406 in it. But, if you buy the car, and it turns out to be a 406 all the better, but if it is the same 352 that came with the car, then you have a quandary, do you rebuild the 352 to keep it original, or put the engine that you want to build in it. All in all, my advice is, if you like the car, and the price is right, I'd buy it. After all these years, there can't be that many left of that particular model. dgh
