Six pack to The summit

Outboard carbs take over?
This isn’t true. The outboard carbs are of a higher flow rating than the center, true, but the center still contributes. I can see that the center carb, being in the center has less of a direct impact on what fills the cylinder over the outboard carb since it has a better placement over the runners path.

Once the carbs are open, there all moving air and fuel.

There is an excellent thread on this at FBBO.
