Camshaft Identification

Hey guys, just pulled this cam from an ‘84 360. Was told by the previous owner it’s not a stock cam, but no idea.

Measured lobe lift and they both came to 0.435” with a 1.5 rocker, so it’s a dual pattern cam. Haven’t found any with that lift, but did find a dual pattern Mopar .430” purple cam. This one isn’t purple, but still doesn’t necessarily mean anything.

Posted pics of cam ID stamping. Shows as follows.

If the int and ex are the same pattern it’s not a dual pattern camshaft !! It’s a single pattern camshaft !!
