This depends entirely upon your location, the year of the car, the Engine, the transmission, the Rear end, and tire size. Theoretically, you could make a Falcon go 200 mph by putting a 427 V8 in it with a 7 speed Porsche transmission and large enough tires.
However: early to mid sixties falcons tended to have two speeds, capping at 55 MPH. Later, they had 3 speeds allowing for 70 mph. Then there's Australian models that can do anything a modern car can do since they're modern.
