Info leaked on the 2011 GT from Edmund's

its about power not size, i have a feeling the raptor has the 6.2 for the obvious torque reasons. if that isn't the case... i have no idea why they wouldn't just let it rock the new 5.0. perhaps they do this because the 6.2 makes the same power as the 5.0 but does it easier so it is less stressed (which is probably a good thing if you're desert racing).

Lets also keep in mind here....the new 5.0L makes the power it does with a near 7,000RPM red line. A tach twisting screamer like that has no business in a pick up truck. The 6.2L is going to be a torque monster in comparison to the 5.0L

Lets also keep in mind....although the power levels on paper are very similar between the 5.0L replacing the current 4.6L 3V engine in the Mustang and the new 6.2L engine replacing the current 5.4L 3V in the Raptor, the new 6.2L engine is making these power levels through truck specific cam/intake set up.....not to mention choking it all through a single exhaust and cast iron manifolds. Oh and lets not forget a power robbing drivetrain. My FX4 eats up somewhere in the 25-30% range by the time the power makes its way to the rear wheels!!!

I would imagine this 6.2L moved into a Mustang would have a shorter runner intake, more appropriate cam profiles for a vehicle weight 2,500lbs less and a dedicated true dual exhaust system with similar tubular, tuned length headers in comparison to the Mustang, in order to deal with it all. Expect power levels to go way...way up in that case.
