heh, good call nosechunks; I will conceed that I didn't really think about "low end" torque, just an end peak torque number available. A V8 would no doubt wtfpwn a 7M at low RPM... wtb boost?
However, to defend my honour:
Torque has everything to do with the size of the crank, nothing to do with overall displacement, and everything to do with anything related to fuel delivery, ignition control, and timing (as that these define how much fuel and air move into the cylinders and how it is burned). Torque is how much work an engine can do... note I said "burning the same amount of fuel", clearly I would be referring to a 7M-GTE in order to burn the same amount of fuel as an engine almost twice its displacement.
How much work an engine can do is determined by how quickly and efficiently it can burn fuel and how much mechanical advantage it has on it's output shaft.
Stock for stock, sure, an old average 7M-GTE has nothing on a new 350 L98... I couldn't imagine arguing that; but when burning identical amounts of fuel at the same efficiency, a 7M-GTE is likely to put out very equivalent peak torque numbers to a standard 350 chevy block. It certainly won't be a difference you'll want to live on. As nosechunks reminded me, the V8 will have a peak torque at a much lower rpm than its turbocharged competition of the 7M, which needs boost to get enough air/fuel into the cylinders to perform that kind of work. The V8 just moves the air required without any aid... this is the advantage of "displacement".
Torque is not a function of displacement... whoever told you that should shave their mullet. Torque is a function of mechanical design and thermodynamic laws... however, displacement is the easiest way to make big torque (and thusly, big power) because it's cheaper to make a big displacement motor move enough air and burn enough fuel to make big hp and tq than to make a small motor make the same numbers... The only replacement for displacement is technology. I'm sure guys like Duane and Nate have spent more on their 7M's than Toyota did.
Torque is the amount of work an engine can do, and work is the amount of energy expended to move something over a distance. For radial torque: that distance is the measurement from the crank centerline to the center of the rod pin, and the energy is how much fuel that engine can burn. Want more torque? Burn more fuel. Big displacement engines are good at burning a lot of fuel with only cheap modifications.
So to answer your question Nick, no, I didn't smoke ganja or something, I was simply not referring to stock N/A motors. I was comparing apples to apples, burning the same amount of fuel. Ya know... like engineering and all that stuff.
