What's faster 2010 Mustang GT500 or 2010 Challenger SRT8?

Yeah the mustang is faster, and there may not even be a U.S. Chrysler next year. But if ther is wanna try and put it up against a 2010 Garlits Challenger? 8.7 quarter mile and NHRA certified. the pro stocker will run sub 7 second quarter mile at 215
