I say 6.0l because you can, and will go bigger and better later. There is always room for improvement if you go with more cu. in. but you can only go so far with the 4.8l down the road.

Turbo 4.8 all the way. DD or not. It will make more avg power, be less impervious to weather, get better gas mileage and get you well into the low 12's if not the 11's being a RCSB and all. Unless you live in RGV, you're not going to get that with a mild NA 6.0. A properly setup turbo 4.8 will cost a lot more than a mild NA 6.0 though...
RGV makes that truck faster? What bout elevation, temp, low humidity, great track prep?
Supporting mods will just help that much more. If u do all supporting mods & a 4.8T, that'll keep u going for awhile.

Wouldn't it be more cost effective later to go 6.0l now, though. I'm not trying to argue at all, but wouldn't a 6.0l in the 1x's be cheaper to build than a 4.8l with the same times.

Find you a rcsb with the 5.3L. They're out there. It doesn't cost any more to start with a little bigger motor. Turbo kit costs the same. Fuel eco diff will be minor and it'll run a lot stronger. The 5.3L will handle the boost just as well as the smaller motor.

I vote for the turbo 4.8L. I think you could get into the 10's a couple times in a 2wd truck @ sealevel with a T4.8. Should be able to run high 11's, in daily driven form reliably, and pull off 20+ MPG. I would do a mild cam, and stud it just to be safe. I think it's possible to run 10's with a NA 6.0L in a 2wd truck but it would have to be a super wild full race deal.

you're going to have a lot of dough wrapped up in that 4.8. a decent turbo is more than a grand. wastegate, BOV, intercooler, plumbing, fuel system, etc. I wouldnt go after it (even doing all the work myself) with less than 4 thousand.
spend a thousand on the 6.0L, replace all the driveline parts that it breaks with stronger stuff, THEN go turbo. JMHO.
