The seal rings are different.....

Camaro = round? Chevelle = Cut off?

Camaros with ZL-2 hoods had a flat bottom until about Sept '69. The grooved bottom AC was phased in at that time for the rest of the model year, 11A, 1969. All of the repros have the grooved bottoms.

Do the 70 AC versions have the notch in the snorkel? I have a GM AC and it has the more rounded snorkel without the notch. It has the 1" 90 U bent tube, not the double 45 degree repro. It also has a lot of forming wrinkles instead of the smooth repro, so I am sure it is GM. It could be an over the counter one, but I'm not sure. Any help? Anyone have a pic of an original foctory 70 version?

I believe the notches in the snorkle was what they were using throughout 69-72 production,and possibly available for a few years afterwards..It's possible there was more then one manufacturer of these and one had a slightly different design then the other.
Your's sounds like a later Gm designed licensed piece to me that is not exactly true in detail to the original design.

I should explain that when I say repop,to me that means a later on manufactured piece,(GM licensed or not),that has lost some of it's original details during translation,to the original part once used on the assembly line.
I understand if others don't classify them that way.

MR70, I hear what you are saying. The thing that has me stumped is the 1" vent tube (used in BB applications). All the repops I have seen have the 2 45 deg tube and are smoothly formed. As you can see in the pic, mine is not I bought this back in the early 80s before the repopers were running. And it was well used before I got it. It has the cut ring. I want to put this up on ebay soon and want to make sure I state the correct origins of this. Opinions welcome! Thanks

The guy I bought my original from, also had an NOS one with the ridge (still in the box, but I never checked for a date code. It had the radiused 90* elbow like the pic above. Can't speak to the notch, as I was not educated enough to know about it. (thanks to Rick, I learned a little more)

Here's an old discussion from Camaros.net ~with pictures~ just about ZL2 cowl air cleaners. http://www.camaros.net/forums/showthread.php?t=54696

Thanks John. Yes, I wrote that article quite a while ago and it was used in the Chevy punch magazine. This air cleaner is the 70 Chevelle one from that article. Since then I was educated about the notch in the snorkle. This air cleaner does not have the notch, but all other signs are correct for a factory GM air cleaner. I'm still trying to figure this one out. Thanks though!
