OK, I made it to the bottom (the bottom for now
) but I do not feel like an expert. I originally wanted to use the large oval finned aluminium air cleaner. I actually purchased one from Finish Line but it wouldn't fit without major modifications to the hood and the filter itself. Paula was very understanding and took it back and replaced it with the rather small round chrome air cleaner which fit without any modifications.
I removed the foam filter element and replaced it with a paper one that was actually too tall to allow the hood to close. I carefully removed about 1/2" or so from the filter leaving just enough space to safely close the hood. I have considered fabricating a replacement for the lower part which would give me an additional 1/4" to 1/2". The outside diameter is 8.5".
I am really confined by the space available to do much else. Now I find that my filter is less than half the size it should be, based on the formula used above. This is certainly much more interesting that the eternal bb vs: sb debate so keep the information coming. Maybe we can all become experts.
