<P> The 1969 season featured the Torino Cobra or Torino "Talladega" which had enough aerodynamic body improvements that it gave it a higher speed than the 1968 Torino, with no other changes . The Cobra, featuring extended nose and reshaped rockers, was renamed Talladega part way through the 1969 season when the Boss 429 replaced the 427 . Starting in 1963 up till this point, Ford had won six straight Manufacturer Championships, and by the end of the 1969 season Ford would make it seven in a row . Richard Petty was tired of winning races but losing the championship, so after a private viewing of Ford's new Talladega and Boss 429 engine, he signed a lucrative deal with Ford . </P> <P> Prior to its first race at the Daytona 500, David Pearson's 427 powered Ford Torino Cobra set a new NASCAR record by being the first to exceed 190 mph when he qualified at 190.029 mph . When the race started Donnie Allison's Torino lead the majority of the race (84 laps). Towards the end of the race the Torino of LeeRoy Yarbrough chased down the Dodge of Charlie Glotzbach, who had an 11 - second lead . It was the first Daytona 500 won on a last lap pass . Things got worse for Dodge when NASCAR, a few months later, finally allowed Ford to run its hemi - headed Boss 429 engine . </P> <P> With Ford winning the majority of the races, Dodge was forced to develop a better car of their own . Using the Charger 500 as a basis, they added a pointed nose . This nose was almost a carbon copy of the nose on the 1962 Ford Mustang II prototype . This radical body shape required a wing to remain stable at speeds over 180 mph . They named it the Dodge Daytona after the race they hoped to win . Even though it never won a Daytona 500 race, it was still a significant improvement over its predecessor the Dodge Charger 500 . </P> <P> NASCAR feared that these increasing speeds significantly surpassed the abilities of the tire technology of the day, and it would undoubtedly increase the number of gruesome wrecks that were occurring . As a result, the 1970 Homologation rules were changed so that one car for every two U.S. dealers had to be built for sale to the public to qualify, hoping to delay the use of aero - bodies until tires could improve . </P>
