Ford fans are an interesting bunch, Ford will tell them whatever and they will buy into it. Meanwhile the 2.3L ecoboost engine in the Mustang uses direct injection, and the coyote engine was designed to take direct injection (based on an article from a Ford fan publication). I only assumed that they didn't need it so they figured why add the cost to the engine, though if the 5.2L Voodoo had direct injection it would have made a bit more power then 526BHP. If you got rid of the durability requirements for the engine and added direct injection then hell 600BHP probably would have been within reach.
Build wise the Voodoo engine is similar to that of the Ferrari F430 engine (which didn't have direct injection either). Ferrari doesn't have to make sure that their engines are reliable up to and over 100,000 miles because that really isn't something that people expect from a Ferrari. People may not expect this from the GT350 Mustang however Ford (like many other mainstream car makers) extends their same practices for regular cars to their sporty cars.
The F430 obviously has a 4.3L engine which produces 80ft-lbs per liter, the Voodoo engine makes 82ft-lbs per liter. The 4.3L Ferrari engine pushes its torque higher up in the band hence it is making 483BHP @ 8,500rpms. The Ferrari engine is making 298ft-lbs of torque at 8,500rpms, it is making 87% of its peak torque at 8,500rpms. If the Voodoo engine was making 87% of its torque at 8,250rpms then it would produce 373ft-lbs of torque and 586BHP at that same rpm. This would push its torque peak up a bit (the Voodoo peaks torque at 4,750rpms while the 4.3L Ferrari at 5,250rpms).
However it looks like that Ford made the choice to peak torque a bit lower and have Horsepower peak at 7,500rpms instead of pushing things up a bit and have even more horsepower at 8,250rpms.
