That's the advertised duration. Best to my knowledge, mopars formula for getting duration at 0.050" is multiple the advertised duration by .777 for stock cams and .850 for their purple shaft cams. Not saying that they aren't available, but I've never seen a actual repo grind of the 340 cam. I was told by a cam rep years ago that they can't grind a true 340 grind because Chrysler owns the rights to all of their engines.
