There are changes for the 1973 Barracuda with the addition of the energy absorbing bumpers to meet 5 mph (8 km/h) government mandated impact regulations. The engines offered initially in ’73 are the 318 and the 340 with a high performance 360 added to the options sheet later in the year. All three of these engines are somewhat detuned to meet EPA requirements, and they all run fine on unleaded gasoline. There is a four speed manual transmission with a Hurst shifter available for the 240 and 360 engines only, but there were as many as three of the 318 also equipped with the four speed, either by factory error or by special order.
