I have a 04 Ram with the Hemi but I know it's nothing compared to the 426, although I've never driven in an original Hemi. It does ok, but I'm sure my 383 Chally will smoke the truck no problem, then again we are talking about a truck. Now I have driven a Hemi 300 and Magnum and between the two the 300 seems to have more of a pickup then the Mag so I can only assume the Charger would be a little quicker. But again, to compare the old and new Hemis...well I can't really do that but hopefully I will one day get a chance to at least ride in an old Hemi equiped Mopar. But at least I can say I have a Hemi!
