One thing I don't like about turbo setups is all the plumbing required under the hood. When you have a really cool looking motor like a Boss 9 or a cammer, all that plumbing takes away from the underhood appeal, I think. I have a twin turbo setup for my Galaxie, supposed to be good for 2000 HP, but I'm going to stick the turbos and intercoolers in the trunk. That way the exhaust will exit to the back via normal headers, and one 4" pipe will come from the trunk, through the interior and up through the firewall to a rear mounted throttle body on a sheet metal intake, leaving the whole SOHC engine fully visible. This approach will cost some power, but I figure I'll have power to burn anyway, since I don't plan to cage the car for anything faster than 8.50s. You could do something similar with your truck, with the turbos in the box, and preserve the underhood appeal of the Boss motor...
