Keep in mind that a drop base may allow you to run a bigger filter, but it will not change the size of the gap between the top of the carburetor and the lid on the air cleaner. If that gap isn't big enough to allow air that has passed through the filter to freely make that 90 degree turn into the throat of the carburetor, you may still be limiting the air flow to some degree. I offer this opinion as a retired aerospace engineer, not an experienced engine tuner.
