Just out of curiosity, if I removed the air cleaners and ran the car with the open stacks, would that help make it run a little leaner?
Yes. It won't hurt but it is impossible to tell the effect exactly until you do it.
You should pick up some noticeable horsepower.
You wouldn't want that to happen now would you?
Open stack Webers are a lot better than filtered. The filters interfere with the ram effect.
You can also do a bit of tuning with them by varying the length of the stack and the opening diameter of the stack.
The filters also muffle the engine a bit as well. Open stacks give you more of a "church organ" effect.
You can hear them on a car in the distance and have an interesting change on the Doppler Effect.
Open stacks will read on the plugs.
