These are the specs for this engine as it appears in the 2007 Escalade:
Horsepower (hp / kw @ rpm):
403 / 301 @ 5700*
Torque (lb-ft / Nm @ rpm):
417 / 565 @ 4400*
Note the low HP peak (at 5700rpm).

Certainly not an expert on the matter, but I would imagine that certainly has something to do with it. They probably also have different cams in them to allow for increased torque.
