Cowl Air Cleaner

[SuperNovaSS]

Are there any ways to determine whether a cowl air cleaner is original, service, or a reproduction? Also, are there differences between the Chevelle and Camaro units? Is an original worth significantly more than a repro?


Thanks,

I seem to remember something about a flat bottom.

I know the early flat bottom 69 Camaro units are worth $$$$$$$ as I still need one for my car....anyone got one reasonable to go to a worthy cause???

Are you talking Cowl Plenum or Cowl Induction?
Early 69 Camaros equipped with Cowl Ind. had a flat bottom.As production increased,that bottom now received a channeled valley,for both ZL-2 equipped Camaros & 70-72 Chevelles.
There are a few ways to determine a repop.
The most obvious being to look at the seam running alongside the snorkle.

Good info. Thanks for the heads up. What does the original seam look like in comparision to a repro? A friend is pulling one out for me to sell. I want to represent and price it right.


Thanks,

On the originals,in the center of the seam it will jog downwards and form a square notch in the center,then continue back on line to the opposite end.
The later repops have one continous unbroken seam.

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?

[Mr70]

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.
