and at 550-575 rwhp it'll be making about 1100 rwtq.

I do my own tuning with Efi Live and my 7000 lb truck went 12.75 at 108.5 mph full weight and no track mods at all; stock engine/turbo, just tuning, exhaust, and water injection. It should go mid to low 12's with the t-bars and tire pressure lowered so it doesn't wheel hop. Oh, and it gets 22-23 mpg on the freeway, and no worse than 16 or so around town. Imagine what it would do in something lighter than 7000 lbs???!!
Although it would be a blast to drive, just realize you'll also receive a fair amount of smack for this swap. If you can live with that, then do it.
