Second, at 450 HP, I'll bet your Mopar has the HP beat with one engine tied around it's back. Just think of the dirt you could move with 2 fire-breathing Hemi's stuffed in there.
That 450 HP is likely at 2000 rpm (or less), at 2000 rpm that is equal to 1181 ft-lbs of torque (it would be more at a lower rpm). A couple of fire-breathing hemi's likely couldn't get the beast moving because they don't make enough torque at the operating rpm range of the scraper.
