dual snorkel small block air cleaner

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.
