Depends on the vehicle/drivetrain/situation.
For SBC's & BBC's that 2200 number is great if you can pull it off on the highway. It's likely that 2200rpm would need a stock or mild cam combo as well. But, even w/a BBC & correct cam, it might be under target for a heavier vehicle that's working/pulling a load.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
