Unusual Air Cleaner
I have already exchanged multiple emails with him on this.
The cover, 1962-66 361, 383 and 413 4-Barrel but has 4-bbl base.
Chrome, 4-bbl, 1965-67 273 4-Barrel
No reference to the unsilenced 2-bbl base for this cover, it was new to him, no idea what applications may have had it.
