This product works perfect for larger 4

September 29, 2013
The adapter is made of beautifully machined aluminum and fits very snugly around the rim of a Rochester 2G carb. It has a low profile and allows for the use of the larger 4 barrel style air cleaners. It's simple to install and works great.
Yes, I recommend this product.

Did not fit my 2GC!!

December 09, 2010
My 2GC is 1/16 larger in diameter. Adapter also interferes with choke butterfly linkage. Lucky for me, my son is a machinist and will have to modify it for me, or I would send it back.
No, I would not recommend this product.

This is for Rochester 2bbl carbs that have a 3" neck for the air cleaner. It adapts to a standard 4bbl air cleaner of 5 1/8". Sorry I do not have an adapter for the smaller 2bbl size.

Will it clear the choke chamber? The choke heat chamber is on top of the air horn and I can't see how a 5 1/8 in ring will clear it when sitting on the air cleaner flange. Is the adapter raised or notched?

Air cleaner adapter number 91011360 is designed to work with a 2G Rochester carb with a 3” throat and to accept a 4 barrel air cleaner with a 5 1/8 mount opening. It sits on the 2 barrel carburetor, goes upward .700 and then out and back down with the flange to accept the 4 barrel air cleaner.

My 2bbl air cleaner opening is 2 5/8 inches in diameter, will this product fit? If not do you have another product made of metal/aluminum that will allow me to install a 4 bbl style air cleaner with a 5 1/8 inch diameter opening?

Bought this adapter along with a spun aluminum air cleaner assembly for a 4bbl carb and the base of the air filter assembly is about 1/2"-3/4" bigger diameter than the lip on the adapter. Is there some part that I'm missing that is supposed to go between them?

The spun aluminum air cleaner base should be for a 5 1/8" diameter carb if number 91011093 and the adapter number 91011360 should go with the 5 1/8" neck air cleaner and if the adapter is different we apologize and can get a replacement the right size. If you have the smaller 2GC carbs the neck of the adapter will likely be too large at 3.00" and require an additional adapter.
