If it is an 8", it will be stronger and easier to modify (separate carrier) than the 8.8"
I have been reading that the 8.8 is stronger than the 8 here on hotrodders.
I have been considering the newer Explorer 8.8 in my S-10 project for the availability of parts and the disc brakes already on it, plus it's the right width without modification.
From my point of view it isn't any different in construction than what I already have (all GM), but it is MUCH stronger than the 7.5 I currently have to remove from the truck.
I am looking at a rough 350 pounds of torque output from the new engine to start with (horsepower is pointless when talking about diesel).
