This was posted awhile back but you might find it interesting:

Questions: (from a FTE poster) Feb. 2010
1.Is the 6.2 based off any existing Ford Engine (or any of its major architecture based off one) - if so, which one, and to what details?
2.What were the major goals of the 6.2l engine over the engines it replaces(5.4/6.8)? (power/torque/gas milage etc.)
3.Most of us are aware, that an "off-road" ~500hp version of the motor was in the Raptor F150's that competed in Baja - was this originally part of the development of the motor, or just a cool idea that the engine team came up with?
4.We know that the vehicle competed the Baja event successfully (and competitively ), but were there any major learnings your team got from the event that spurred a change in the design of the motor?
5.Are the power figures that were available in that Baja vehicle indicative of versions of the engine that may be seen in the SuperDuty in the future?
6.Most of us are aware of a 7.0l ~700+hp version has been used in race vehicles too - is this also indicative of future possibilities for the SuperDuty?
7.Was the 6.2 designed to easily support the possibility of Direct Injection in the future?
8.The 6.7l engine has shown some unique design characteristics, not seen on truck previously (twin compressor wheels on single shaft/exhaust in the engine valley etc.), does the 6.2 also have some "trick bits"?

Answers: ( by a Ford Engine Engineer)(copied from previous FTE post)
1.The new 6.2L is all new. It shares nothing with any of the other V8 or V6 engines in the Ford Powertrain line up. The bore centers are 115mm, compared with the Modular 100mm bore centers. This allows us to have a relatively large 102mm bore, and make decent power from a 2 valve per cylinder engine.
2.The major goals relative to the Modular engine it replaces were as follows.
a) Competitive horsepower and torque with the other manufacturers trucks in the marketplace. The modular 100mm bore spacing limits the bore to approx 90mm. The long stroke of the 5.4L, while great for low speed torque limits engine speed due to piston speed - so it's hard to make much more power out of it without expensive materials.
b) Fuel economy uncompromized. 2011 Superduty owners should get better gas mileage than the 2010 w/5.4L and significantly better than 6.8L.
c) Durability. This is a pure truck engine.
3.The Baja Raptor R motor was a one off, designed specifically for the race in November 08. We were asked by the SVT team in August 08 if we could provide something for the race, and the team went to work. The engine ran great for the entire race,
4.Not really - but it was a great validation of the thousands of hours of durability testing that we had already completed. For example, the team overheated the engine during the race because the fan relays malfunctioned. They got the fans working, filled the engine from their water bottles and continued without issue. We do similar dyno durability testing called piston hot scuff testing, where we run the engine as significantly elevated coolant temperatures.
5.Future product discussions are off the table - sorry.
6.See #5
7.See #6 and #5
8.The does not have any significantly new design approaches. Rather, it's well executed robust design building on years of experience and lessons learned from our other truck and car engine programs. It's designed with reliability and durability in mind, while delivering great torque and good fuel economy.
