Cal Metal:
Yes, "three". They are lined up perpendicularly to the row of cylinders, and have a "progressive" linkage. I assume this means that the middle one opens first, the the two end ones open as you put your foot into it.

Three would be set up like this > ::: (horns) or ||| (carbs)
(Think in terms of looking down on the top of the engine from the side)
Four would set up like this > :::: (horns) or == (carbs)

I thought the system "looked pretty cool" and the note from XK's says that it is "streetable". Not sure if the cool look would be worth the trouble I suspect the webers would bring.

Cheers,
