Let's see here

2994cc at 6,000 revolutions per minute, but it takes 2 revolutions to fire all six cylinders, and you have air flowing through the intake only 1 of the four cycles.

In 6000 revolutions, a single cylinder will have 1,500 intake events.

A single cylinder in a 95 x 70.4mm engine displaces 499cc.

The firing order is 162435, which is also the intake event order, so you have alternating intake pulses that start at the front of the left bank and work backward, and the back of the right bank and work forward (in direction of travel). So you never have two cylinders on the intake stroke on the same bank at the same time.

So, you have 499cc of air being sucked in 750 times per minute per bank, that's 374 liters of air.
