N96 air breathers. 383 or 440

I want these to be for a 440. But my hood doesn’t close easily. Can anyone shed light on these.

This style with the small round lid is similar but measures differently at the crossbar. Reader Mike Brodin provided the following measurements.

Height from bottom of air cleaner throat to top of crossbar

383/400 - 2 1/2"
340/440 - 2" QuickBpBp from Moparts provided the following images. If you set the air cleaner base on a flat surface, such as a table, the carburetor throat for the 383 and 400 will sit completely on the table. On the 340 and 440, the outer edge of the air cleaner will hit the table and the carburetor throat will not. You should be able to slip your fingers underneath it.

Thanks for the response. So based on the pics…….any opinion on which one? I think they are both for a 383.

Anybody have this bottom measurement?

Here you go. 70-72 440 base.

SWEET. Exactly! Can I cut one of mine down to fit?

You could try but getting that rolled base straight and level so it seals to the carb will be a challenge. Better off buying a 440 base and sell the 383 one to offset the cost.

Are you sure the air cleaner is hitting the hood?

 

[DasFusca]

Yes. It won’t close. It’s tiring the rubber seal.

I listed them for trade in order to get the right one.
