Well, the folks at Dodge claim that the 4.7L makes 235hp, while the 5.7L Hemi generates 345hp. Of course, this is measured at the flywheel so, with an automatic transmission and drivetrain taken into consideration, you have to subtract roughly 25% of that number to figure your power at the rear wheels. Hope this helps.
