C1 Single 4bbl Air Cleaner
I'm trying to determine the correct air cleaner for my car. 1957, single 4bbl, serial number 2642. What is on the car is not correct, it has a replaceable filter and spacer between the air cleaner and carburetor to clearance the choke. There is an early model and later model for 57's and I can't get a clear answer on which one is correct. Hoping there is someone on the forum that will know the answer to this question.

The original single four barrel air cleaner was a sealed unit. Here's a picture of mine from my 56 several years ago. 55's used the same cleaner except the bottom was different because of the choke housing clearance. Real one's and repro's are expensive. I think they are 10 1/2” in diameter.

Very clean engine bay. Yours is correct for early '57's as I understand it. There is a different shaped, but still sealed for later units in that year, I'm trying to determine if I'm early or late in the production cycle based on the serial number.

To my knowledge there is no difference between early or late for the 57’s. The small two four barrel air cleaner was only 6 3/4 diameter but not used on a single four barrel.

The corvette 1x4 air cleaner is the same for all 56 & 57 corvettes, The 55 1x4 cleaner is very close to being the same except for the base plate.
All 56 & 57 cleaners had an indent in the base plate for the choke housing to set in .
I believe that Roys picture shows the 55 base plate.
I have attached a few pictures off my 57 showing the indent in the base plate
