Did Dealers remove SMOG?

[Chevy454]

In one of our Camaro reference books (I can't remember if it was Hooper's or McNeish's) it states that all '69 cars came with smog, but that it had been rumored that possibly the low HP 396 Chevelles may have not had the smog...or something to that effect. I know our Camaro has the untapped manifolds, which I see occasionally, which makes me wonder if there was possibly more than 1 car that came without the smog. But, who knows?!

This is a very interesting topic. Did anyone have a chance to speak much with the gentleman that was the original owner of 2 Yenko Camaros? Maybe we need to pick his brain!!!!!
