Quote: I also have the " 383 four barrel " pie tin instead of the Magnum but have the un silenced air cleaner which the original owner said came factory on it. Also the black breather cap not chrome.
Mines exactly the same (black Oil Cap, "383 Four Barrel" tin. The duel snorkel) AC may have been a California deal, part of some lame noise reduction attempt? Tough to say but my car was an LA build car so it makes sense.
I think the dual snorkel was probably because it's not a Road Runner or Super Bee but this brings up another question. I think all the high performance B-bodies and A-bodies came with a chrome oil breather? It was the only dress up in the engine compartment. Maybe yours is black because it's a 330 horse SW? Now I wonder if the 330 horse 383 Super Bees, RoadRunner's and Charger R/T's with air had a black oil cap? My 340S Barracuda with air has a black cap but I don't know if it's the original but it's a very unmolested car? I'm going to put a chrome one on it.
