the correct air cleaner for a 62-66 4bbl 383 is the small round lid that was used on slant six truck engines and A/B-body 225s starting around 67-69ish. on my 66, I used a slant six top on an aftermarket chrome base of 8" or 7" dia. the base is hidden, and the top looks correct. the earlier ones didn't have the vent pipe for the valve cover breather., by 65 or so , I think they had the vent pipe lid. see the 3rd setup pictured here: http://www.nicksgarage.com/aircleaner.htm If you want the look the big 64-65 426S housing, I used a common 14" aftermarket base with this top: http://www.autohobbydigest.com/msl/?5293 that used to have a snorkel on it. didn't pay to have it chromed, instead painted it black. as far as hood clearance goes, if you use the base from a cheap aftermarket chrome air cleaner setup, you can buy a shorter filter (say 14x2" instead of 14x3", or 7x2" instead of 7x3") and make up any clearance issues you have... ---- Please address private mail -- mail of interest to only one person -- directly to that person.
