horsepower 360/ 390

Darnnit! I thought I saw somewhere horsepower rating for 5.7 Hemi to be 390...A hemi is a hemi I thought.At least 5.7 one.Tonight I saw an add for Dodge trucks in an ATV magazine.Yes,390 HP. I thought I just made a mistake last July so when the WK2 I was buying only had 360HP.I said what the hell,and bought it anyway.I'm happy with the car but really wanted the extra power . What's the difference?

The RAM intake manifold is a two stage internally, to add power and torque. Not sure why it was not used in the WK2's and the 300/Charger.
