Yeah, that horsepower number on a ZL1 is a bit exaggerated... he does have a point about the (midrange of the) torque curve, though.

The LT4 should have almost the same torque at 4000-4400 rpm as it has hp at 6400-6500 rpm, and both curves should have more of a bend than his graph shows, with both essentially linear and torque basically a flat line that feels "clamped" between 2500 and 5000 rpm.
