need to add the 69 coronet RT, 440 4 speed , power steering only. would absolutely bury the 160 mph speedometer. the Tulsa police had 2 1968 furys, that the factory guaranteed would do 185 if kept tuned. my rt had the same drivetrain, w/ the exception of being a 4 speed. the T.P.D. bought them because the Camaros were getting on the b/a expressway and outrunning them. my ex partner worked at a Chrysler dealership at the time.
