Overall Assessment

Customers appreciate the product for its high-quality, durable metal construction, distinguishing it from plastic alternatives which can crack and deteriorate. Users commend it for its practicality; specifically, it effectively solves the issue of attaching a modern chrome air filter to smaller Carter carb tops, even fitting dual quad 1962 carters. Users also found the product to have an ideal fit, keeping the air cleaner low for hood clearance. It offers a snug fit, although some note requiring mild filing due to a somewhat rough cast. Customers would buy again, despite price concerns, indicating superior performance and customer satisfaction.

Works if your going 4GC style carb to newer edelbrock air cleaner. However, it's non flippable if you want to go the other way. Edelbrock carb to old air cleaner use Speedways #910110691

does the job

It works as intended but is a snug fit due to a fairly rough cast. May need some filing. Price may be a little high for what it is.

Really rough casting, but with work, it will work.

The casting is really rough and would not fit right away. Had to use a file quite a bit and then a rubber mallet to make it fit.

This is a one of a kind item that solves a big problem of adding a modern chrome air filter to the smaller Carter carb top on an original 1957 chevy.

The air breather adapter I had was hard plastic and it cracked and deteriorated. This one is alloy so I shouldn't have to worry about that problem with it.

Kept my air cleaner low so it cleared the hood, exactly what I needed. Bought a plastic one from elsewhere that was too high.
