What you find with more "athletic" powerbands, as it's been called, is a later onset of torque and a peak closer to 5,000 RPM and HP that continues to build past 6,500. Even the LT1 in the GT4.R has been rebuilt for higher RPM power, which likely sacrifices lower RPM torque for an expanded powerband.
So an LT1 is "truck-like" since it's peak TQ comes on 500RPM higher than the truck version, but the Coyote is not, even though it makes peak TQ at the same RPM as the LT1 and only 400RPM higher than it's truck version.

But the Coyote is more "athletic" since it makes peak power only 500-600RPM higher than the LT1?

So which is it, 500RPM of power is the difference between a truck engine or an athletic engine? It can't be both. Either the Coyote is a more athletic truck engine or the LT1 is a truckish athletic engine?

Personally I don't subscribe to either "inaccurate" generalizations. The Coyote needs more RPM to make the HP of the LT1. The LT1 needs more displacement to make that HP. Two ways to reach the same goal, both with their own positives and negatives. Like you said, you move the RPMs up and you lose power down low. But that doesn't expand your powerband, you just moved where the "meat" of it is. It's always a give and take, hence why Ford geared the auto up significantly to catch the SS with A8 to make up for the lack of TQ.
