the more you up the torque, the shorter the engine lifespan... by a LOT!

At 2050 torque, you'de be doing good to get 650k miles out of a highway truck as it is before the head had to come of it vs. close to a million miles at 1750-trq.

It is far cheaper to replace the rears with a better spec than it is to torture your engine.

Thats what my thoughts were... the more power these guys want out of the motor, the shorter the overall life span is. You'd think once you explain to the driver that you can get a million miles outa your motor vs. 600k they'd want to leave it alone. But they keep on wanting more power... I must be missing something. Most of these guy's trucks are their paychecks, you'd think they'd want to keep them outa the shop.

A side note, most of these trucks aren't flat landers, they fly through the rolling hills of Appalachia. Maybe thats why they're hunting HP? Would re-gearing trucks still be better?
