Can I see your air cleaner?

Seems right. I've always seen them on unsilenced (no snorkel) air cleaners. Funny thing is that there appears to be no difference between the Super 6 of 68 and the plain old 225 /6. If there is a difference, please enlighten me. It does not show up in any of my books.

Not the case when the Super 6 showed up in 76 with a 2 bbl carb. These has a Super 6 decal in blue, but similar in style to the 4 bbl muscle cars of the late 60s and early 70s. The air cleaner housing had a snorkel on it, too.
