    Big Block vs small block Air cleaner Differences?

    How do you tell the difference between a Big Block and A Small Block Air Cleaner assembly. I am looking for an original for my 1966 small block L79 car.

    I think I found one, but the owner has no idea whether it is for a Big Block or a Small block. Also he is not sure exactly what year of corvette it came off of.

    Were there differences Year to year in the base or top of the Chrome style Air Cleaner?

    Any pictures would be appreciated.

    Thanks,

    Nick

    The top lid is the same. On the bottom plate you will see three flat spots where breather tubes will be for differant applations. The L-79 will have a tube in the one that is all the way back at the center line.

      Would this base be from a small block?

          This would be a big block air cleaner. Your L-79 should have the tube in the area where the flat spot is on the bottom of the air cleaner in this photo.

            Pic - From my 1967 Unit

            Here is a pic from my 1967 327/300. I believe (but I will stand corrected) that it is the same as the 327/350.
