Well, for all those "5.0" owners who over the last five decades have felt a little embarrassed or deceitful -- and by all means to those who don't even care and simply love their 302s -- it is time to rejoice. After a 16-year hiatus, the 5.0 has returned in the 2011 Mustang GT and, yes, at 4951cc, it now officially displaces five full liters. Better yet, thanks to all-aluminum construction, twin independent variable cam timing (Ti-VCT), and a 6800-rpm redline, this don't-ever-call-me-a-4.9, 32-valve 5.0 liter cranks out 412 horsepower at 6500 rpm and 390 pound-feet of torque at 4250. (A run on the dyno at K&N Air Filters in Riverside, CA, suggests actual output to be around 435 horsepower and 404 pound-feet.)

They have a full page of their testing results somewhere on the Motor Trend website but I cant find it at the moment, that mention will have to suffice for now.

Ford officially says 412hp that's it. So on paper Chevy is on top. Now, when they start going to the track we shall see who is on top there. Ought to be fun.
