1965 Offenhauser 273!
I agree. It's one of the best looking air cleaners ever. Probably too small for a high horsepower motor, but more than enough for a less than 300 cube motor. Shoot, Chrysler put them on some four barrel big blocks in the early sixties - 361s all the way up to 413s (only they were painted black, not chromed) .i'm partial to the chrome 273 charger/commando air cleaner.
i think that's what ma mopar would've used as they had it and it flows well for what it is.
