Wow, a 2.75" pulley on a 5.3. Does that make about 13psi for you? That torque is awesome for a 5.3, no doubt. Very cool, thanks for posting these.
Throw a little larger blower cam in that truck and you'll see those HP numbers rise.
With that drastic drop in power on the big end, I'd bet you have some belt slippage as well.

Nice!
Have you done anything for belt slippage so far? An SS owner was fighting bad belt slipping issues ast month. He posted up nice torque numbers, but power was dying in the mid 4000s. He corrected his belt slippage issues with a new belt and updated his tune, no other physical mods. Torque only went up 30 but hp went up 90+.
