Technically, that's correct. However, in stock form, most of these larger engines have pretty close peaks. My torque peak is at 3200, HP at 4000, with plenty of guts down low as well.

Regarding the gear thing, I'll agree that while low gearing helps acceleration, it's brutal on the top end. My Jeep rips 0-60 in 6.8 seconds, but runs a 1/4 mile in 15.2 at about 90. Once you break 70 or so, and it's out of 2nd at WOT, it's done as far as moving fast. Fortunately, gas mileage prevents me from going that fast anyway.
