Now that I have my Super Six setup, and am contemplating replacing the stock unit with something a little more modern. What works and looks good on the two barrel setups? Thank you.

Hi, J. Goodman, that depends upon how much you value good looks over practical solutions. It also depends upon how much room you have under the hood, and the climate you are using it in. The stock air-cleaner for the Aspen/Volares sits low over the carb, and has a provision for heated air to prevent carburetor icing, as well as for a cold air hose taking cold air from the inner fender like stock F-bodies, or cold air from the front if you prefer that.
Air temperature directly effects power. Cool air is denser so a more air (oxygen) actually enters the engine.
A 7.2 degree change in air temperature causes a 1% horsepower change. So if the air temperature under your hood is 180 degrees and the air temperature in front of your hood is 90 degrees then by ducting the cooler air to your air cleaner inlet you can give your engine a 90 degree incoming air temperature drop for a 12.5% increase in horsepower (90/7.2 = 12.5).

Using an open chrome air-cleaner looks very nice, but has it's drawbacks.
