Check out the new Car & Driver.
The new Shelby GT500 ran a disappointing 12.9 @ 112 mph. Not really any faster than the previous 4.6 Terminator Cobra. (Hopefully we don't have another '99 Cobra fiasco happening.)
The Corvette ran 12.8 @ 113 / 0-60
-- They also raced two low-milage examples of the '68 GT500 & '68 427 Vette.
'68 GT500 -- 13.9 @ 103 '68 427 Vette -- 13.8 @ 105
