That sounds about right.
The problem is - and I experience it with the Avlanche is that GM has cut back on the oil pressure in some of their newer motors and the engine in the truck only has about 45 PSI cold idle and has about 10 psi for every 1000 rpms above that.
With no redline in the tach and you can almost take the engine to 7000 rpms with no effects to the motor. Except for the one time when I had the transmission in manual, I have never hit the rev limiter. In first gear, with a 6 speed transmission and 3:23 gears, that was about 40 mph and about 6,000 rpm's.
