It seems like with everything they have done to engines the manufactures still can't get past the old adage that there is no replacement for displacement. After reading all the input it seems the big blocks still produce their torque at low rpm's and the small blocks produce their torque at high rpm. So a 5.3, 5.4 or a 6.0 will need to get up to 35-4500 rpm to pull while a 8.1 or 6.8 will do the same at 2500 rpm. It sounds like the 5.3 and 5.4 will work but be on the edge of their comfort zone. The 6.0 may be the best compromise between power and economy. The 6.8 and 8.1 are probably overkill and use more gas but will not even be close to their potential so will be more relaxing to drive.
