    Just an FYI: if you want to run a big dry filter element cleaner and can't find one that will fit your 2G since most air cleaners are for four barrels, Speedway Motors sells an adaptor specifically for adapting a 2G to a four barrel air cleaner. :) item 910-11360 $14.95 each.

    Also there is a k&n filter/cleaner that will for your 2G WIHOUT the need for an adapter. If you measure the diameter of the 2G's intake and go to K&N's website you can search by sizes etc. I have been running this rig on my CJ5 for around 4+ years and love it.....I'll try to find the part number to my aircleaner and post it...also IF anyone wants pics just let me know I'll be happy to take some and post them.

    Most companies do make the aircleaner base in a 2 5/8" body they just aren't stocked and have to be ordered.

    to the best of my knowledge, my paper element air filter and carb adapter came off of a late 60's/early 70's Chevy truck. I'm not sure which chevy models/years came with a 2G, but it fits and works perfectly.

    maybe so, most FLAPS I have been to recently don't have anything like that, although I remember seeing them before. Just listing an alternative. Speedway has some cool stuff, lots of dirt racer stuff, but if you are running a 2300 cc Pinto in your flatty, they have hop up stuff. They also sell 2G carbs, but some are pretty pricy$$$. Also a source for small (350CFM) Holley 2 barrel carbs and heim joints for doing the tie rod mod listed on the tech page. That is where I first heard of them. Just some harmless info.......:)

    I am running a paper element and I got the adapter at the parts store. It is a Mr. Gasket and it clears all linkage. It was not too expensive either. Just my two cents though.

    Ahh, this thread's been comatose for 10 years. [​IMG] [​IMG]

    Since I was unable to PM you, would you mind posting pics of your open element air cleaner and sharing the part number?
    Hopefully you're still running that K&N setup.

    In fact, anyone reading this feel free to share photos of your 2G running an open element/paper filter setup.

    I'm trying to fix the Bubba-made baling wire and chewing gum fabbed air cleaner the PO had on this Dauntless of mine.

    My Jeep came with an Edelbrock open air element filter with a plastic adapter to fit the 2G carb. It has been removed and the oil bath put back on.
    Here's a pic

    Beach66Bum: I’m unable at this time to see your pic on this fickle Apple product I’m using. :confused:

    From what I am seeing, most of the currently available air cleaner assemblies that require NO adapter for the 2 5/8” (inlet diameter) Rochester 2G are for a small air filter/air cleaner housing no larger than say 6 inches+/- in diameter. Such air cleaners are ostensibly intended for the hot rodder’s triple 2G carburetor setup to ensure there is no intereference from the other carburetors in the row.
    I don’t want one of those small air cleaners in the interests of maximum air flow—I think they are quite restrictive on a single 2G because of the lack of surface area.... plus they look awkward. :sick:

    I understand that if you’re going to run a 5 1/8” to 2 5/8” air cleaner adapter (which opens up a ton of 4 bbl air cleaner options), this billet aluminum (not plastic) one from Speedway is the way to go, I just have not seen or read of what is involved in the install procedure or any discussion of the finer points——i.e. it appears you’d need or want a gasket top and bottom for maximum sealing.

    I just wanted to see someone’s entire setup, ideally using the Speedway Motors adapter part #91011360.
