180mph in second gear?
The link to the Dodge Tomahawk makes sense, but I don't recall the Tomahawk ever making it that fast. They claimed it could do 300+mph, but IIRC it never did more than about 1/10th of that in actual testing, unlike this Plymouth.
IIRC, the Tomohawk kept falling over so it never really went over 20 or 30 mph. It was simply unrideable. Such a shame because that was a thing of beauty IMO.
