i just dont see it... i have the same truck basically as you do, with longtubes and intake on 32's and i have to floor this beast to keep up with traffic off of a redlight... i see these things running an 18 or so at best. this transmission is a slushbox, its geared too low for "racing" and not to mention the 4.10 rear and all the power that is robbed transferring through the big 14b rear.

wow, my 1500 with 6.0 LT, Full exhaust, 4.56 gears, Costum tune, and some other goods, I ran a best of 14.7. Stock I was 15.7 and a lot lighter than a 2500. Best I can see a stock 2500 run is a low 17 high 16

What's the time calculated on 105 mph in the quarter mile? Because that's what I can get my 5 speed, 6.0 HD up to in a quarter mile stretch outside my neighborhood. Its exactly a 1/4 mile too between two road signs so I'm not just guessing.

Go to the track and see if you trap 105.
