This is all I could find that fits under the hood. I have the Stage V intake and Holleys in a 65 Cornet with the engine set back 1-5/8". (e-body k member)

The 60 Dodge I'm buying comes with a complete long ram setup but it also comes with a set of those air cleaners that I may put on an Edelbrock CH28 with some Carters instead of the long ram, can you still get filters?

Possibly !

I did some digging around and K&N apparently makes one! Also looks like WIX and NAPA make paper elements still

Remember,if you are running a CH28 and want to use the oval air cleaners,you have to run AFB's.Also there will be no clearance between the air cleaners,the carb spacing is about 3/8 closer than the factory intake.

Here is my factory intake,everything from a 62 300H,

Can you use AVS's on the CH28?

You can use them but you're going to have an issue with air cleaners.

Are the air horns different sizes?(think they're the same) or is there some sort of interference? (Linkage etc)

the older afb's had a 4 7/16" air horn. the avs's and edelbrock afb's have a 5 1/8" air horn.

Ah, Thx for the heads up

Anyone looking to buy, i am liquidating my extensive 35 year collection, of parts.
I am a pm away.
