MM&FF are idiots. That 7.0L experimental is a Hurricane/Boss engineering exercise codenamed 777 for 7.0L, 700 hp @ 7,000 rpm. Apparently it must make over 700 hp on E85.
SOHC, 2V, 2 spark plugs per cylinder. You can find better pictures of the engine in Don Bowles car on the 'net. You'll see it has a Modular style timing chain cover, a dead giveaway for overhead camshafts. Also note how far back the #1 and #5 intake runners sit from the front of the engine. Does MM&FF really believe Ford just wasted all of that space for no reason?
The video gives a better idea:
