Talking about unresponsive: the 5.0l engine really has a hard time with the 2.2 tons of that rig! I would´ve thought it´d be a bit sportier then it was. The 2.0l Diesel in my 1ton + DD has way more punch and i would´ve thought: twice as heavy, but two and a half time as much CUI... should be at least equal in response/acceleration. It´s not that bad, just not my expectations. I should´ve known though: it´s a truck and it drives/accelerates like one.

In your case I'm betting the original owners never did a proper gear swap. Your engine is simply operating outside of it's nominal powerband. Also, this can cause premature wear and tear on the Automatic transmission. IIRC this model used a E4OD unit that wasn't well known for it's strength.
The 302 is known for great gas mileage and is good for normal driving in larger rigs (I had a 302 in one of my vans), but I can see how they may be underpowered for certain driving styles or conditions.

Once it reached a certain point (speed/rpm´s?) after shifting, you could tell that all of the sudden the acceleration got a lot better. It´s that dead unresponsive time after shifting up that made it seem unresponsive to me, i guess with the right gears it´d be totally ok, because it was totally ok once it reached that certain point after shifting.
