thats right down my alley, will be a blast when done! you going to run a th400. Havent messed with the 4.8 but ive heard they are pretty strong, done a buch of the 5.7, 6.0 and a 8.1L

those headers / feed pipes are interesting, never seen one done like that, the up and over. it will should work grate, usually they are all hidden some place, we had to do it the Y under the truck and run it back to feed the turbo on the 8.1L it worked good but ad a little lag. not that it mattered once on kill
