Duel!

Forgot the star of the movie was a 71 Valiant! 2 sixes and an 8 were filmed, look for the V8 badge in some of the shots, and see if you can see the odometer throughout the movie, the lower radiator hose should not have blown on a car with less that 5500 miles on it! (but probably didnt damage the 'ol six now, eh?) The '55 Peterbuilt couldn't go over 25 mph during filming but very good cinematography made it look like it could do 80. Pretty cool movie just for the car shots themselves.
