Can someone please school me on 340 air cleaner

Have my 70 340 air cleaner put away and been running one of these on my 418 stroked 340 for years. I removed the decal... Only has the little "Filter Maintenance" decal now.
Always loved the look and plenty of Air Flow. I do like the look of the stock 70-71 340 Air Cleaner though.
