I went out and played with my 1500HD driving out to one of the well pads. I can brake torque it to around 2200 rpm and then flash it around 2400 rpm or even a bit higher. Bone stock 1500HD that weighs in the neighborhood of 7500 lbs.
And the talk about STR is very important when talking convertors. An efficient 3000 convertor will drive just as nice as stock and still tow just fine. Or you can get a sloppy one that is just a pig to drive. 3000 would be great with that cam, and mpg is nothing great to start with in these trucks so a little worse is not that noticeable. Once locked however the stall speed doesn't matter making highway driving mileage virtually identical.

The stock 80 converter is not a performance oriented converter, it's aimed at durability. That being said, at the same time, I doubt anyone recommending a 3000+ converter for towing purposes has used that setup. Dave @ Yank recommended a 3200 for me, as I still towed but not major. I think he said it would be good for 3-4000lbs. I decided to go with the 3600 as everyone says "go one bigger" and you'd want to pull your hair out trying to tow with it.
When it comes down to it, there's only so much you can do with 364 cubes in a 5500lb truck, let's face it. Even with the 4l80e mine rips at WOT, but can feel lazy just putting around town. Also the gearing of the 4l80 isn't helping matters getting up and going.

7500lbs sounds like way too much. My 1/2 ccsb z71 with 1/8 tank weighed 5510lb and the brother inlaws 2500hd 4x4 with about 1/8 tank gas was 6250lbs. I know the scales are within 10lbs of our local track scales too. So if your saying your truck is 7500 maybe the extra weight is causing it to flashing higher
Um yeah it does. That's the truck a loaded 12X40X48 Weatherguard Pack Rat, another 60" Weatherguard tool box in front of it and then the junk in the back of cab that replaced the rear seat. I know..... I actually use my truck like a truck and not run around empty because it's just a rolling tool box for me and makes up some of my charge out rate. The convertor flashed the same before I made this truck into my work pig...... I didn't specify that in this thread so I apologize.
