Good observation. Cams, indeed. Actually there are FOUR of those suckers in a beautiful DOHC layout with very high flow heads. Expensive to do but a tuner's dream. The intake manifold is maximized for torqued, but a replacement tuned for horsepower would be a consideration.
Don't forget that our engine is a truck engine. It was based on the Infiniti 4.5L V-8 car engine, but substantially modified to emphasize torque at expense of horsepower. But the 4.5 has variable valve timing on both the intake and exhaust valves. Look to see that come over to the Endurance engine soon.
Then a programmer/tuner chip that can optimize hotter cams and variable valve timing can make some magical things happen with this very advanced engine design. I don't see OHV engines being able to match the power gains. That's why NASCAR makes everyone stay with pushrods and carburetors and why CART and Formula 1 engines produce insane amounts of power from small displacement.
