There's no single MPH (miles per hour) for a 1973 Dodge Charger. The top speed depended heavily on the engine and drivetrain options chosen. A base model with a smaller engine would have a much lower top speed than a high-performance model with a larger, more powerful engine. Furthermore, actual top speed is affected by factors like road conditions, driver skill, and vehicle condition.
Therefore, you can't give a definitive MPH figure without knowing the specific engine and options of the particular 1973 Dodge Charger.
