Correct me if I'm wrong but the 5.8L GT500 is the most powerful production V8 at 662hp. Not only does he have more power but he is lighter too. Probably the only way to beat him in a 1/4mile is to have 550+awhp and launch faster than he does.
Edit: forgot about the Hellcat at 707hp. GT500 is #2 most powerful production V8
