273commando engine dress up wiw
67 with CAP. (Clean Air Package
The valve covers are 66 and older.
67 has the PVC in a grommet on the pass side cover.
As for years
I believe 65 thru 67, A bodies perhaps even B bodies.
The package would have been on 4bbl, 10.5:1 compression 273s
On Plymouth models it is called Commando, on dodge models it is called Charger
65 and 66 have 2 breather tubes 67 only has one.
As for value.
75 to 125 for the valve covers.
50 to 75 for the air cleaner
That's all I would have pay/ed
