IMHO… Street Truck 4x4… I would not get too high on the RPM Range, that will take away drivability.
Higher RPM Range, less Lower Torque Spec and less sit of the pants feel, also if off roading then higher RPMs will be needed for running a trail.
Don’t start fooling around with Torque Converter Stall Speed, you think drivability goes away quick with a high rpm cam, up rev your stall speed and you will lose drivability so fast it ill make your head spin.
Now if this is a 2x4, then we maybe talking another story.
If drag racing, high rpm and stall speed is the name of the game.
