***UPDATE*** Additional information has now leaked out, with the new 5.0-liter V8 making 412-hp at 6500 rpm and an impressive 390 ft-lbs of torque ***UPDATE***

It’s official, the 5.0 is back! That’s right… we learned today that the iconic 5.0-liter will return in the 2011 Mustang GT with an impressive 412-hp. This information was released today and was embargoed until the 28th, but after a loose-lipped individual leaked the info, we’re certainly not going to sit back and miss out.

The output is still short of both the Challenger SRT8 and Camaro SS, but those vehicles weigh hundreds of pounds more, so the added power, combined with the ‘Stangs more nimble chassis should make the already superior performer a unanimous winner in the muscle cars wars.

Ford is set to debut the car at the Detroit Auto Show, and the return of the 5.0 was expected after Ford debuted a new 305-hp 3.7-liter V6 for the base Mustang at the LA Auto Show.

AutoGuide will bring you full coverage of the official debut on January 11th, unless, of course, more info is leaked… because we’re currently sitting on a long list of technical specs that will have five-oh fanatics drooling.
