Original cam part # for a 72 400

Does anyone know the original camshaft part number for a 1972 400 engine?
Or, suggest a good OE grind camshaft?
I am thinking about using a new old stock camshaft in my "factory fresh" engine build to cut down on the chance of wipeout from Chinese metal. Plus I liked the very smooth idle I had with the original.
Thanks,
-Jon
