With the pistons looking like they are directly opposite of each other, what does the crank look like? Does the engine use a typical crank of 4 connecting rods to 4 separate crank lobes, or is it 2 lobes?

That's more properly termed a horizontally opposed engine or a 180 degree V, since the pistons are on the same crank pin. A boxer has each pair of pistons moving toward TDC at the same time. This cancels out the tendency for the engine to try to rotate about the axis perpendicular to both the crank centerline and the cylinder bores. VW, Porsche, BMW motorcycles and Subaru are boxers. Ferrari made several 180 degree 12 cylinders which were not boxers (opposing pistons shared a crank pin).
