GM open element air cleaner with a chrome base?

[3macs1]

Hi Eric:
I am not much help either other than I took an air cleaner identical to that off a unaltered small block 72 corvette probally 25 years ago.Like you I thought the base was not GM but now after seeing yours I am not sure. I know I still have the lid with the GM marking , wing nut and the chrome tube somewhere but think I tossed the bottom thinking it was not GM. The more I compare that base you posted to a black GM one the more I think it is GM just a matter did someone chrome it or did the factory do it.
take care

Joe;

The owner of the air cleaner was/is under the impresson that it came off of a `70 LT-1 `Vette, so maybe you're not too far off?

Did yours also have the dimples to clear the needle&seat adjusters on a Holley carb like this one?

Hi Eric:
I honestly cannot remember but the car had a 4spd muncie and I am positive a 780 holley factory if that is possible in 72??
I am not up on the small blocks

Mac, wasn't 1972 the last year for the LT-1 engine in the Vette and Camaro..?? so a 780 Holley would have been the carb...

Corvette guys are funny. (No disrespect; I used to be one ) I've seen this done a number of times. They (we) just didn't like that Black rim around the bottom of the air cleaner.

Could it be a factory piece? Who knows; it's this old "always & never" deal again, but my money would go on it being a day-2/dress-up project.

I think it's aftermarket too. I circled a part on the attached picture that makes me think that. It is shaped like the areas some aftermarket air filters hook a hose to suck up oil fumes from the valve cover vents.
