I would turn that around on you and say that Scott's manifold seems to make a good argument that dual plane manifolds have an unfair reputation for only being low rpm manifolds. This 393 cubic inch motor hasn't run out of air at 6600 rpm. It hasn't made peak horsepower yet either.

That's a reasonably big cam, the dual plane manifold will provide better intake manifold vacuum for PCV, power brakes, vacuum advance and auto trans modulator valves.

I agree however it would be nice to bolt on a single plane from Terry Parker or TFC and see how the motor performs with a single plane manifold.
