Some Background - Dual Carburetion On 200 ci Four Bangers
* Angle Of The Dangle:
The Model A and B Ford engines are mounted to the frame at 3.5 degree angle (front high).
Fuel and air can be mixed in a dual carb progressive setup, but often the mixture can be rich. 
By making the front carb the primary (the one that works all the time), it allows a bit more time for liquid fuel to roll back, vaporize and balance the fuel charge.

* Progressive Dual Carbs 
Most Ford Model A and B after-market intake manifolds are designed with the carbs at the far ends of the manfold.
This design causes uneven running and poor tuneability when used in progressive set ups.
In tandum they work nicely with smaller carbs.

* How Many Carburetors Are Best?
One Stromberg 97 or one Ford/Holley 94 is spot on, in CFMs, for the Model A and B engine's 200 cubic inch displacement.
More carburetor CFM's are a waste of time, energy and money - the engine can't use it . . . .
Unless you have built your engine to breath better: larger intake valves, higher lift, longer duration camshafts, porting and polish, headers and a higher compression cylinder head of at least 6.5:1.
Keep in mind that the more air you can get in, then more HP/torque is gained  . . . .
But after it is in, it must combust with greater pressure to be effective.
Many believe 7:1CR is the engine's sweet spot for touring, sport and racing.
All modifications change things, so choose carefully.

* Best Manifold For Progressive:  
An Intake manifold with carbs close together as possible, with a mixing plenum and interior directional vanes to blend the air fuel mix.
Our "Equalizer" 
(and "Riley Two Port") dual downdraft manifolds have the best of both worlds:
The look of duals, with an actual mixing plenum whereby all fuel is fully equally mixed and runs equally out to each port.
The "Equalizer" is excellent as duals, progressive or with the forward carb the primary 
(Stromberg 97 is a good choice) and the back carb as dummy.   Nonetheless, the second carburetor should not kick in until the RPMs have reached 2,500 RPM (+ -) . . . and that will be a mear crack of the second carb's throttle plate(s).
A second dummy non-functioning carb can be hooked to lingage, or not, with a metal block off plate and 2 gaskets to keep it from functioning.
The 
"Equalizer" is the only dual carb intake manifold that has these features. . . . Just saying . . .
