There are other factors besides the actual diameter of the converter that play into how it launches your vehicle. Connverter weight as well as the converter's STR play a large role as well. The stock converters are very heavy compaired to aftermarket equivalents of the same diameter which use a billet case. Throw in small diameter which decreases case and internal componet weight, you get significantly less rotating weight at the crank. Most quality aftermarket converters have a much higher STR that a stock (or reworked stock) converter as well. According to you sig, your truck looks to be set up pretty well. You shouldn't have skimped on the converter. 
Get a good 9.5" or 10.5" aftermarket converter and I bet you will see some sub 2.0 60fts. Just FYI, I had a Yank TT3000 when I had about the same mods as you on a 5.3L (h/c/n2o/full bolton) and it did pretty well. I switched from it to a Fuddle HPTruck (9.5") and the truck came out of the hole much harder. I am currently running a Fuddle 9.5" in my 4L80 and pulled a 1.77 60' at Irvington a few weeks ago babying it out of the hole on 305/45/18 Nittos.

Wow, that really suprises me. I even pulled a 2.0 60' with a friends VHO when it was almost stock with a 245/70R17 General Ameritrac (spare winter tires) on it (spinning a bit also). There's a guy with a Silverado SS that pulled a 2.03 60' with only a CAI, cat back exhaust, and programming. That's a 5400lb truck on heavy *** 20's.
TX, those are a great street tire. The quickest 60' on a 20" wheel (2wd) is one of my goals.

alright! i just picked up a 3200 fuddle 9.5" verter from a member here.
probably send it in to the manifacturer for a clening/higher flash to 3400 or so, then test it out.
i am thinking this should be just what i need to blow my transmission up!
