63m 64 and 1965 small block air cleaners.

[Bruce B.]

Does the correct 1963 340 HP air cleaner have the single tube in the bottom section that connects to the oil fill tube?
On the 64 and 65 high performance (small block) engine air cleaners are there 1 or 2 tubes in the base?
I know that one of them is the large (about 1") but I'm not sure a small one is present.
Thanks.

In 64 and 65 Holley carbs were used and in 63 they used a carter carb. The carbs have different size openings so the air cleaners are not interchangable.

Just Carter carbs were used through 1963.
In 1964 Carters were use don every engine except the 365 HP.
In 1965 Carters were used on 250 and 300 HP engines and Holley on the rest
1966 was the first all Holley year.
