Brings back memories.
A long time ago we had a 1976 Peterbilt 359 dump truck with a 8V92 and 13 spd, and that thing was a screamer that would turn heads.
I can remember hauling to a new development that was at the top of a hill for a few months. And I would be pulling that hill working through every gear, splitting the top gears. It was funny every time I got to the top of the hill everyone would be looking to see what was coming, roofers on the roofs, framers, and on and on.
I actually kind of miss that truck, it had lots of power and revved up quick. So you had to be fast with the gear box.
