The horsepower will be relatively easy. But from what I gather, getting that torque will be a tall order. Most DI engines I've came across generate about 76 ft-lbs/L, strangely this is nearly universal. It also puts the torque at 380 ft-lbs, which compares favourably with other 5.0L engines out there. This Coyote V8 will need 80/L to hit the 400 mark, for a naturally aspirated production car this is extremely rare (bordering on practically never). That includes exotics that squeeze nearly everything they can out of their engines.
So look for the 2011 Mustang GT to have a 400 hp /380 ft-lb 5.0L engine, getting probably 17/26 for fuel economy. The car will probably weigh about 3600 lbs. A drag race will come down to the smaller details like traction, gearing, and not least of all ... driver skill.

I was talking with a buddie that works in a ford plant and said they were talking about a 6.1 liter that will replace the 5.4 in both the cars and trucks. I guess we will see. And I know you said DI and naturally aspirated but my car made 130ftlbs per liter at the motor and now makes about 200 ftlbs per liter.
