This is not only a "what's it worth?", but it's "what the heck is it from?" It's a dual snorkel air cleaner with only the GM sticker with that number on it. It is for a quadrajet and looks like it only takes a 2", maybe 2 1/2 inch element on it. It came off my 67 camaro, which was bastardized with drivetrain parts from other camaros and also some corvette stuff. The air cleaner also has a chrome lid with a GM 327/250 hp sticker.

The number doesn't match anything in the 75 and older Chevrolet book. Goes back to 64. Might not be chevrolet.

The number is for the sticker it self. Sounds like an early seventies Corvette air cleaner.

I found it on Ground Up's Nova site. It's a 62-79 Nova air cleaner($175 new). Man my car had parts on it from at least 4 GM vehicles! Never trusting evil-bay again!
