I have come across a 1958 Fury that has what appears to be a factory installed 200 MPH speedometer. I cannot find anyone that is aware of such, although I have been told that the factory installed these speedometers on the hemi cars that were made especially for the government, and they were used by 'revenuers" specifically to chase moonshine runners. Again, the speedometer is not an add-on and certainly appears factory. My research can only find 150 MPH Speedometers from factory. I was also told the government issued cars were not entered into records like normally built cars were, so therefore there may not be records showing these faster cars. I would appreciate any info you may have on this. Thank you.
