Ford Mustang GT 390 in "Bullitt", 1968

1968-Ford-Mustang Bullitt, Steve McQueen, canopy - This is probably the only film unmodified Mustang ever. It has enormous 325 horsepower, the heart of a true American muscle car is under the hood - the aggressive 6.4-liter V8 engine, 4 speed manual transmission [which seems very difficult Shift] and drive the rear wheels sport for fun corners. What else needs a real muscle car for the persecution, especially in 1968?
