Then, by that logic, you should run 2 1050cfm Mighty Demon or Dominator carbs. In reality, this would make the vehicle essentially undriveable.
More than once, I've picked up power with a SMALLER carb. Most memorably, replacing an 800cfm carb with a 625 on a Mopar 318 (in a 1969 Dodge Dart) was worth almost half a second, because the car launched MUCH better (more torque), and the smaller carb was ample for a 318 at 6000RPM. I've seen Ford 289's Hi-Po's perk up considerably when replacing the big Holley with a smaller (~600-650) carb.
At 100% volumetric efficiency (which I'm nowhere near, with low compression, small-valve heads, & iron exhaust manifolds), my engine (a 460, not a 429) spinning 3800RPM requires about 500cfm.
