looks to have 8 2 bbl carbs that would be a bugger to jet properly so the engine could idle in order to make it street reliable. they would absolutely have to be flow bench match tuned I like that custom fabricated 10 or 12 inch rise deep plenum tube manifold sitting on top of the Hemi though
With 8 carbs one would be positioned over each tube leading down from the plenum even thought eh chamber would be common for all of them the one closest to any given tube is going to spray down that tube more than it will mix with the others in the plenum. The 1 advantage of the large plenum chamber is there would be a balanced vacuum through out though the atomized fuel would largely be gravity driven when a given intake valve was open. the rapid opening and closing of the intake valves creates a negative and zero pressure pulsation
A v8 engine with a 3 duce set up will actually run better on 2 carbs than it will if 1 of the 3 is over or under fueling or has an early or late throttle response setting I would think this may even be compounded with 8 carbs.
Of course just like a duel quad or a 3 duce the 8 duce could take advantage of having progressive throttles and idle on 2 or 4 then run on 4 to 8 and power on the 8 secondary's
