If you follow the F.A.S.T and Pure Stock racing series, Buick, Pontiac, Chevy, Ford and Mopar all win and loose their share of races. Stage 1 Buicks, Super Duty Pontiacs, LS6 Chevies, Super Cobra Jet Fords and Hemi Mopars all run within tenths of each other and it's more a function of the driver and prevailing conditions that decides who's winning.
The first car to break into the 10's in the F.A.S.T series is a 69 427 Corvette. It's absoultly amazing that a car on skinny bias ply tires can run that fast.
