I stand corrected! Though the throttle body is used for some control as mentioned. While there is No "Cam" in the classic sense, there is an eccentric shaft which is, in a sense, a cam..
After reading more (at 370Zdotcom), I see even more hindrances with this system to improving intake performance with classic techniques (Throw that out the window!). Forced induction should prove interesting.
