Big block air cleaner
« on: August 19, 2017, 09:41:57 PM »
Now that all the old photobucket pics are gone, could you guys help me ID this air cleaner?
I just bought it. Any thoughts about it? It's supposed to be original. I believe it is. Anything amiss? I bought it to replace the stolen one off my 69 back in the 80s.

Thanks.

Dave when I looked into these, it seemed that style of base you show has been observed on original 302 engines - the angle (~30 degrees down from horizontal) and orientation (clocking) of the breather tube on the underside was the difference. The other common style seen  has the breather tube with a 90-degree bend and different clocking position, but I couldn't get a clear understanding if that was for a different engine (most likely imho) or a different supplier or a service replacement.

Ed (bertfam) has posted some great references from the various P&A catalogs which show just how many different assembly part numbers were used, and without the air cleaner base having a stamped number, it may never become any clearer than by trying to look at as many unrestored examples as possible.

The lid and silk-screening appear correct for the 69 MY, quite a lot of threads about the change from curved to straight print.

Thank you very much guys. I'll check out those links. FWIW, I believe the open air cleaner for the big block was the same one used for the 302. What you said sounds promising Tim.

I'm all set Jimmy, but thanks.
I couldn't have asked for a better buy. I thought the chrome was pealing and it turns out it's just remnants of the sticker. The chrome will all clean up nice. It really turned out to be an excellent assembly line cover. Here are a couple of pics I took last night for future reference.
