Streetmaster to Airgap

Because the engine didn’t demand or couldn’t move more air at the time it was done.

Good observation. So its safe to say that the engine wasn't really handicapped by the tiny manifold runner that's way smaller than the 360 head port?

Your scoff at the RPM VS the lower restrictive intake because there’s no great leap in power on a low demand engine is funny as hell.

Your assertion. These 2 intakes are at opposites ends of the spectrum. Doesn't look like that engine needed all that much air flow to make 230 Hp at the wheels.
