Glen,
Exact reasons I bought the 4600LP, even tho it had the same engine as the For SD or pre 450 15K gvwr, or the GM 3500HD ie a pre 4500 15K gvwr. The REST of the 4600 was much more truck. I did not need nor require the HP of a DT466 or 360. Altho I admit at times I wish I had the 235/620 T444E, but that would have been another $6-7K, $10K for a DT like you have which would be the cats meow for how I use my truck. Mostly local doing under 55 mph, a few forays on the interstate at 60, now where legal per say to drive over 60 for 100 miles N, S, E or West for that matter.....
At the end of the day, it is choosing the truck that fits ones needs and desires from a carrying standpoint, power/speed standpoint, and gearing such that one can go up a certain % grade with out stalling out! be it lack of gearing but power there, did that with many 454/TH400 1 tons, or lack of traction.

With all the talk about the proper tune and intake/turbo/exhaust parts for the 7.3, I think the right combination is right there, in
bold print.
Whatever International did to the T444E (7.3 Powerstroke, in Ford terms) to make it produce 620 lb-ft, reliably, in a high duty cycle, commercial application, is what the 7.3 needs in our old pickups.
Find that information, and there will be the answer to the question of how do we upgrade the 7.3 to produce greater power, while still retaining the reliability and longevity it is known for.
235hp and 620 lb-ft is more than some DT466's produce. There are many ratings for all of International's engines.
