Some late ford pickup have a dual throttle body, don't know if it staggered
opening, then the v-8 Chevy Tuned Ports use a dual butterfly throttle body.

More Torque and HP per given cam.  Cam size is determined by application.

For a MAP system the common plenum might save ya a bunch of work for getting
the MAP signal filtering right
