Actually, I had a 2000 with the 4.7 for my first 4 year stint, and the current 05 HEMI gets the same mileage (HORRIBLE, LOL) as the old 4.7. The HEMI has a chip, 3 inch exhaust with a Cherry Bomb Pro Series muffler, and a few tiny tweeks. Estimated 370 to 380 horse. Pedals in this one are stock adjustable. On the 2000 I had put 2 inch blocks on the pedals so I could reach. My route has a few sections where it is a couple miles of straight stretch with no stops, and I have had both Durangos over 100 MPH driving from the passenger seat. Yep, I'm a crazy Fokker. The Jeep is a mixed bag. About $25 a day cheaper on gas, right hand drive, and super maneuverable. But, manual drums, 2wd, weak-suck 4 cylinder, no A/C, and a heater that won't keep your toes from going numb if it's below freezing outside.
