It's actually 390 hp and 407 ft/lb.
What did you have done to each truck? My Hemi is loud as hell in the engine. When I hammer on it, you don't hear my exhaust in the cab, you actually hear my engine. That's my K&N pulling in all of that air.

Just because the 4.7 may be louder at the TB doesn't mean it's flowing more cfm...it could just be the two different engine designs.
