Champion radiator - I cut her open

Hmm, all makes sense.
I did find this in my stash of goodies.
Looks like mopar part number 46237.
Is this oem for my 383, 67 barracuda?
Funny it's painted nearly identical to my paint code of PP1. There are traces of this color on the floors, however I'd assume the engine would have been Chrysler blue from factory.
