I believe it was a 1966 Cobra 427 that was specially prepared for the banks and it hit 199 MPH at Daytona I think it was on the long straight. That is really moving for that car with the lack of aerodynamics and I don't think I would have wanted to be the driver. But they were trying to see how fast they could get it to go.
Now 40 years layer and billions of dollars in technological advances and we have cars that can go 220.
