I saw a picture I think it was smokey yunicks chevelle where he made an enclosed air cleaner element and piped it through the firewall to catch the cold air from the windshield vent. Has anyone tried this with a camaro? Im thinking of customizing one with aluminum. Any suggestions or experience with this would be greatly appreciated. If you got pictures even better.

I've thought about doing that too, if I had a fiberglass cowl induction hood, since they don't have the hole like the steel hoods. I'd make the opening in the air cleaner assembley about the same size as the opening in the hood where it meets the cowl. And make it out of steel so you could smooth it all out with body filler and paint it the same color as the car. Just my thoughts.

If that's the picture I'm thinking of, where a duct comes out the pass side, and back to the cowl, the very early cowl inductions for Z/28 were done that way. If I recall, it was a dealer installed option. (Don't know if it was in the trunk, or parts counter product--Anyone know for sure?)

I considered a nascar style cowl induction on my camaro its a cool idea. I have a firebird cowl panel its shaped a lot different tha a camaro and looks neat with my L-88 style fiberglass hood. Maybe a stock car specialty company would have and pre fab assembly I've never looked.

How about a factory crossram with cowl plenum air intake!
My friend has #17 of the first 1967 Z/28s. It was a Trans Am car and is restored that way.
There is a picture in the Web site 1967Z2/8.com. Look under the Z gallery for Don W car.
There also is a 1968 Z locally that had the factory cowl plenum set up. It looks cool.

I say take the nascar one and turn it to the passanger side and fab the rest similar to the one on top.

What would you guys suggest making the duct that would connect the air cleaner to the firewall out of?

After reading this thread I really like the idea of making my own.

You won't believe this but I saw this car today at a show in Waterdown Ontario. It was for sale for 48,000 Can. (about 32,000 US)
It seems to be a piece of hard plastic that is screwed to the firewall, and the breather
fits into it. This is the same as the one on my friends 67 Z race car. I will ask him what it is made of and where he got it.

I checked with my friend, and the Cowl plenum that he has is over 30 years old. It is for a 1967 cross ram Z/28. It is one of the only ones that are known to exist, and if you have Hoopers book there is a GM spec sheet on it in the back of the book.
He said the last four barrel one that he saw sold for over 2500 dollars. They are made differently for each year and they were sold as a dealer add on in the trunk of the car along with the headers.
Carl Dwiggins a famous Chev dealer apparently made some repops of the four barrel induction but only sold about 50.
To say the least they are ultra rare.
I know this is not a solution but it is interesting.
