I found this cool 1/4 mile calculator surfin the web. It is for motorcycles, but it's one of the better ones that I have seen. Seems like its accurate too, except for distinguishing autos vs. manuals. I started the ratios in 2nd gear, not 1st for the stick, and kinda guessed at the torque/rpms. As far as friction and stuff goes, beats me, but this makes me want to bomb the truck some more. 16's aren't gonna cut it.
