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
Looks like something George Barris would have cranked out. I remember making some cool model cars back in the 60's!
I would disagree with you Ken. Those carbs are in a common plenum so it is only the total outcome of the plenum that must be in tune with the engine. Depending on how the plenum is designed with baffles, each carb does not have to be in the same AFR as another.Quote:

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
Looks like something Ed Roth could have built...
Or it could be a trailer queen, built for looks and not run at all.
The era tells me an operative engine in place, the radiator size how far it could drive, the grooved for street tires say progressive throttle linkage.
Body work is very creative, but bubble dome just ruins the look for me.
