Now, how much you need and want, is relative. I drove my '50 1 Ton for 3.5 years full time with a 216. I few times I hauled a 6000 pound trailer. It was slow doing that.
Now, the panel I drive has a 235 in it, and has 50% more power, the panel also weighs 1000# less. To me, the panel drives like a scaled cat. It's so fast!
However, the panel is no match for a "modern" truck, neither in cruising speed, nor acceleration!
