Wow! How many different types of air cleaners came on 67 Firebirds? I always thought the chrome pancake type came on 400 motors. Then there was the std black body and lid. Then there were the AIR versions too, which were different somehow? Did they have the black body and chrome lid version like 8-9 had? Only difference in the later years were the 350s got a small round snorkle opening and the 400s got the oblong opening and a chrome lid as far as I know. They didn't make an AIR version in 68, right?
Makes me wonder if that chrome pancke trype for an AFB that I got with the 66 GTO intake might not have a crossover application afterall.
