What is the right air cleaner??

[69rag500]

Im working on my 69 rag that has a 383 4 barrel with air. I have seen both types of air cleaners on 69 383 cars. What is right????

I've seen both on original cars...

 

[F4R/T]

335 hp unsilenced, 330 hp silenced?

335 hp unsilenced, 330 hp silenced?

Back in 73-77 time frame I had a buddy with a Charger 383 w A/C which should be a 330 hp that had an unsilenced air cleaner.... So I don't believe that is what triggers the air cleaner selection..

Depends (at least partially) on whether it has a California noise package.
(Silenced air cleaner, hood blanket, turndown tailpipes, instead of tips.)
Has it got a holley or a Carter?
