1965 Dodge Dart Charger

That right there is an unsilenced air cleaner, p/n 2465 310, originally installed on '64-'65 Barracuda (only) with 273-2bbl, not used on California-sold cars.

'66 version had different baseplate; the clamp band style attachment gave way to the bail-and-wingnut variety.

Same lid used on (some) '61-'67 slant-6s with a 1bbl base, and (in chrome) on 273-4bbl applications.
