Big Block Exhaust Manifold Comparison?

People often forget one thing. The cylinders aren't firing at the same time. It's not like that's not TONS of room for one cylinder to fire at the time. You're working with pulses here. Dissect one and you'll see there's a good bit of room there.

True, but if a motor was spinning 5000 rpm that would mean any given cylinder will fire about 41 times per second. 4 cylinders on that side of the engine would be 164 firings per second. Seems like a a lot of exhaust to ram through that reduced orfice. My math might be messed up but the idea is that it’s ALOT of time per second per cylinder?

Regardless the op doesn’t want to hear that I think it would be less power and others have said they noticed no change in performance, so I’m out! Haha.
