And I would like to correct some information on Bullitt, McQueen was YANKED from the driving, as he screwed up too much, and couldn't drive. Bill Hickman (who drove the awesome triple black '68 Charger R/T 440 4 speed) was the real stunt driver here.
Also, to clear up any misconceptions about the Stain being fast when compared to the Charger, here is a quote from Max B., the guy who worked on and built both the Charger and the Stain, for the movie.
"I'll tell you this," said Max Balchowsky, "I was really impressed with the Mustang after I got done with it. I didn't think it'd make that much difference beefing it up. Later, we took both cars out and went playing around with them over by Griffith Park (near Los Angeles). The Dodge, which was practically stock, just left the Mustang like you wouldn't believe." Ron Riner has similar recollections. "The Charger ran rings around the Mustang. We trimmed the tires down (on the Charger), we practically made them down to bicycle tires to try and handicap Hickman, and Bill just run them."
That is from a motor trend article about the film that is here:
