What you're probably seeing are people who have switched to Weber carbs, which come with the small, rectangular air cleaner. Note that the small air filter will get dirty a _lot_ faster because of the reduced surface area. Also, it may not run as well when it's cold out, as the standard air cleaner will pull heated air from near the exhaust manifold when the engine is below a certain temperature.
