I struggle with this concept. I think if the car has doccumentation about a CE ebing installed, it would be right to do that. If the original motor is just missing, I'm not sure how it is really much different than any other option.

I guess it is slightly more plausible that a CE motor could have been used under warranty, but without doccumentation where does it put you?

It is just as plausible that the original motor was decked for a re-build. I realize there are ways to bring a decked stamping to the surface. I think the argument of which is more acceptable boils down to wich one is easier to disprove as being an actual occurance.
