The whole torque vs. hp argument makes me want to sucker punch someone in the liver....
Torque produces exactly ZERO work. HP produces work. So we throw around the term torque to represent low rpm HP under the curve. What we should be measuring is HP at the bottom and top rpm of every shift. That's your average HP pulling a trailer from 0-75 mph. In a trailer pulling drag race between a hot 350 vs. a mild 454 it doesn't really matter where the RPM is as long as the gearing is right for the powerband of the motor. But obviously a small cubic inch motor with low gearing isn't going to last as long or operate as nice as a low rpm big cubic inch motor.
As Erik the Awful said: "Power under the curve. Power under the curve. Power under the curve."
My twin turbo 3.5 Ecoboost in my Taurus SHO has way more low end HORSEPOWER than my old 454 TBI (and a Vortec too). You could build a twin turbo 6.0 LS motor too for a truck application that would eat the NA 454's lunch day in and day out. It doesn't have to be an 800hp 7,000 rpm drag motor.
I'd choose a high compression NA or mildly boosted 454 every time over the stock or stock tuned 6.0 LS for a towing application though.
