4.6 3v with open valve injection?
I found this article on the jalopnik website and find it kinda interesting, Specially the part that is in bold lettering.
I also heard a rumor while back about FRPP working on revised 3v heads.
Could this be the 2010 mustang engine?

All-V-8 Powertrain Lineup
The new F-150’s engines do more than sound good.
The 5.4-liter, 3-valve Triton V-8 has been optimized for better performance and delivers 320 horsepower and 390 lb.-ft. of torque running on E85 (85 percent ethanol and 15 percent gasoline), pure gasoline or any blend in between; 4X2 trucks equipped with the 5.4-liter V-8 are EPA estimated to achieve 14 mpg city and 20 mpg highway – a 12 percent improvement versus the previous model. Fuel economy when operating on E85 will yield different values than gasoline.
The 4.6-liter, 3-valve V-8 is new for F-150. It delivers 292 horsepower and 320 lb.-ft. of torque and competitive fuel economy on 4X2 versions of 15 mpg city and 20 mpg highway. Both the 5.4-liter and 4.6-liter 3-valve V-8s utilize open valve injection. This unique feature improves the flow of fuel into the combustion chamber and allows for more precise control of the combustion process. This results in an increase in horsepower during towing and higher rpm operations along with an improvement in emissions.
The 4.6-liter, 2-valve V-8 is the third V-8 choice in the line-up and delivers 248 horsepower and 294 lb.-ft. off torque with the same fuel economy numbers as the outgoing V-6 – 14 mpg city and 19 mpg highway on 4X2 versions.
All three engines are full LEVII capable meeting California’s Tier 2 Bin 4 tailpipe and evaporative emissions regulations.
