I don't know a gas engine that makes it's peak power at 2,500 RPM. Not one; not even a big, big block or even the EcoBoost.
With todays electronic EFI engines, red line is set by the computer. When pulling a mountain firmly plant your right foot to the floor until you go over the speed you want to go and then hold it at that speed.
It's really that simple.
Not really.
Most of the info comes from Ford owners with the V10 which has to be run at a high RPM to produce enough power.
Where as the Chevy Vortec like the OP has the peak torque occurs at only 4,400 rpm.
The torque curve of the 6.0L is broad and flat, with approximately 90 percent of peak torque available at only 2,000 rpm.
