Looks like Adam is right, this is a 1972 with single snorkle.
The one I have has dual snorkles, it did although have the "340 CI" stickers on the lid prior painting, could this have been out of a Road Runner or something else, or did someone swap the lid or added the stickers, it was orange.

Thanson the pics are in your email.

that air cleaner has a little trap door under it also for more air when you floor it.... a dual snorkle probably came off of something else and someone changer the lid.
