There are regular cab short bed 6.0's with just an SCT with Erics tunes running 13.0x's... it's pretty impressive. If you want to run 11's with a stick shift, you're going to have to do a TON of work. Do your research before committing to this, 11's are not easy in a 3/4ton truck without some heavy mods.
You're probably better off paying a shop to do the chop on the frame. Or do a TON of research on that too, but since you asked already, it tells me you really don't know how to go about this (I doubt many do, pretty sure it's somethign I wouldn't attempt...).
This has been done many times though so there is info out there, just try searching around. The most popular and widely documented is probably stroked lightning... A guy named Gene built it, he goes by weweld on multiple forums.
