Texas-size braggadocio started this retro-car rumble. Back in January, famed Houston-area tuner John Hennessey released plans for a 705-horsepower, ZR1-engined 2010 Camaro. Naturally, this sent forum boards buzzing about when and how Ford would respond with its 2010 Mustang.
Not two weeks later, a white-hot press release out of Las Vegas landed in our inbox, detailing Shelby's plan for a 725-horsepower Mustang GT500 Super Snake. And just like that, the ultimate musclecar battle had begun. The easy match-up would have been simply to let these two braggarts throw down in an asphalt octagon, but we wanted more. So we set about arranging a 700-horsepower trifecta and went looking for a Challenger with enough swagger to go tire to tire to tire with Shelby and Hennessey.
