Had someone ask me the other day-"Which car in "Bullitt" was really the fastest?" The answer is the Charger. Ford supplied 5 Mustangs, all 390 / 4-speeds. The problem was the 390 was a truck motor-tons of torque, but not really a high-performance platform. Ford hastily made the 390 an option in 1967 becuase you could get a 396 in a Camaro and a 400 in a Firebird. All a 289 Mustang was going to see of a 396 Camaro or 400 Firebird is the taillights. Sadly, that was true for the 390 as well. Motor Trend tested a 396 Camaro, a 390 Mustang, and a 400 Firebird in 1967. The Camaro was the quickest in the 1/4-posting a 14.8 second time. The Firebird posted a 15.1 second time, and the Mustang a 15.6. That may not sound like a lot-but in drag racing 1/10th is one car length. So the Firebird smoked the Mustang by 5 car lengths, and the Camaro did it by 7. That's not even a race. Anyhow-Ford had the contract to supply cars for Warner Brothers. Steve McQueen didn't want two Fords in the chase. He thought it would be hokey to have the bad guys driving a Fairlane. GM and Chrysler refused to help out-citing Ford's contract. So McQueen and Cary Loftin-the stunt coordinator bought the Charger off the showroom floor of a Bay Area Dodge Dealer with their own money. The Charger was a 440 / 4-speed. In early practice Bill Hickman-the Charger driver, left McQueen and Loftin ( who shared the duty of driving the Mustang ) so badly that they couldn't even film it. Steve McQueen was furious. Cary Loftin and his chief mechanic, Max Balchowsky-hopped up one of the Mustangs with headers, and shorty glasspacks, an Edelbrock intake and 750 Holley carb and a Mallory distributor. That's why it sounds so badass on the soundtrack.  The Charger was still quicker in a drag race, but now they could film it, without Hickman having to slow down and wait for Loftin / McQueen. This happened other times. In the "Smokey and the Bandit II"-director / stuntman Hal Needham had a big problem. In the first "Bandit" if he or Burt Reynolds wanted to smoke the tires, it was easy-with the 400 cubic inch '77 T/A's. If the stunt car was a 4-speed, just pop the clutch. If it was an automatic, powerbrake it a little, and then floor it. ( If you watch the film sometimes you see a clutch pedal and you can hear Reynolds shifting it. In other scenes you can see the automatic shifter on the console ) However by 1980-the 400 inchers were no more, and were replaced with the anemic 301 Turbo. ( Honestly-why didn't they just buy some low-mileage '79's with the 400 Pontiac and 403 Olds engines-they'd smoke the tires and wer e'nt even a year old ) Hot Rod magazine howled to the high heavens. Their 400, 4-speed '79 test car ripped off a blistering 14.61 in the 1/4. ( Hot Rod was faster than all the other buff mags, because Motor Trend, Road &Track etc-launched with"some wheelspin" and all shifts were lift-throttle-they all ran 15.20's.) Hot Rod revved to 3,500-4,000 rpm and dropped the clutch hard-which allowed the posi-equipped T/A to rocket off the line. And they powershifted. Hence the much quicker time. Anyhow-their 1980 Turbo model while supposedly only being down 10 hp from the 400's-couldn't smoke the tires on dry pavement!! It ran a 16.30 in the 1/4. Ugh. They didn't have anywhere near the power of the 400 inchers. So Needham had nitrous oxide installed on one of the 1980 T/A's used in filming. It was strictly the "Burnout" car. It's said the stunt crew of the "Rockford Files" used '78 Firebirds until the series ended in 1981 because star James Garner didn't like the front end of the '79-81 models and said they were "dogs" He was right. The show went through several gold Firebirds in it's 1974-81 run. Some were Formula 400s, some were base models. We know the 400s had balls, but even the base models usually had 350 Pontiacs which had some oomph. The last '77-78 models-even thought GM was playing musical engines because of smog laws- in the base model in California-you could get ( I'm sure the producers used California models ) a 350 Chevy, which still ran pretty damn good. The non-turbo 301 V8 of 79-81 wheezed out 135 hp. That's why they were "dogs".  The "Dukes of Hazzard" wrecked 216 '68-70 Chargers during the show's 1979-85 run. A funny story-the stunt crew of "Dukes" and the stunt crew of "Knight Rider" had a friendly contest. Most of the Chargers they wrecked were clunkers-some 318 2bbl models. The Duke guys put a healthy 440 in GL26, and some Koni shocks, and aftermarket front and rear sway bars on it. The Knight guys figured the WS6 suspension of the '83 T/A was good enough, but they swapped the 305 for a Traco-built 350 crate engine. I don't remember who won, but I remember reading an article in a magazine that the stunt drivers griped constantly after ward that the mechanics couldn't make all the cars run and handle like GL26 or "Super Kitt"!!  Mastermind
