Florida,
The leaking bowl won't effect your performance..it is in a "non-sucking" area. Don't let the sounds of the carburetor lead you astray. A full flowing carburetor is noisy, even a little old Rochester. You are using a small, aftermarket air cleaner..this exacerbates the noisy situation.
If the truck isn't running right, it will usually tell you. It will pop and backfire at high RPM's as it starves for fuel. It won't start correctly or will get horrible mileage. Remember what you are driving, an OLD truck with a low tech engine. If you want FAST, you will need to buy a brand new F-150...WHAT, HUH, @#%&?$
