I found the CRG website and was blown away by the wealth of information. It's amazing.
I have a '67 Camaro I, in a way, inherited. When I got it there was a hole in the passenger side firewall that lead directly into the cavity below the cowl vent. I was told that it had been put there to mimic a type of rare induction. My car didn't come with it of course. I was told that originally, if a car came with it, there would be an enclosure around the air filter and a tube that would lead over to the hole in the firewall. Essentially, it would give the car cowl induction through the vents in the cowl.
I've never seen or heard of this and I assumed if it were real I would have found it somewhere on the CRG website. I doubt it's true, but I'd like to make sure. Can anyone verify this to have been true? I suppose it could have been offered on 67-69 for all I know?
