A twin-turbo Viper V10 stuffed into a Plymouth Cuda body sounds like a garage fantasy, but Legendary Motorcar Company actually built it and then drove it through a snowstorm to prove it. Chrysler’s own engineers had to inspect the car at the Chelsea Proving Grounds before it was allowed anywhere near a high-speed oval alongside a Ferrari Enzo. At 190 mph the windshield trim tore loose – and the driver kept going anyway. Just how fast did this homebuilt E-body ultimately run against Maranello’s finest?
