VIN typo is nothing.How about a complete engine typo.I almost bought a 71 Cuda that was a Hemi.Had hemi badges ,vin, window sticker etc.Only problem was it was a 440.This wasnt some hacked up used car.Brand new on the floor at dealer.Still kick myself for not buying it as dealer offered it to me cheap.Supposedly there was at least one more known in IIRC Chicago.This one was a red vert.Rocky
