I like how the venturi's are closer to each corner of the intake ports..
Makes me think instead of a single plane would something like a cross between a single plane and kind of a mini tunnel ram with a large two barrel directly above the front and rear intake ports so basically a two piece 4bbl (inline) would work better than a 4 bbl straighter shot easier to make same length runners. And run the carbs side ways or even slightly crooked to get an even straighter shot.
