67 Baldwin/Motion chevelle 427

[GTO_DON]

Maybe you can answer this question I asked about this car before. When did the 427 emblems go on the car?? You can clearly see it has 396 emblems on it in the old pics.
Also Are you sure about it being the only 67 ss Motion car built that year? Back around 1980 There was a burgundy or plum 67 SS427 that used to stree race at the meadows around here and it said Baldwin Motion on the sides of the car!! Wonder if that car was real because I did not think anybody was cloning cars back then.
