While the dodge tens are stout, they get spanked by the ford 5. 4 and ford ten... . unloaded. Load em up, and the dodge ten will WALK AWAY. Same relationship exists with stock CTD and tens, for the most part. Now the modified CTD will blow snot over most things out there.
I have spent a fair amout of time in the ford ten and PSD. while usually quicker off the line, throw a hill at them or a load, they will stat gasping, transmission will downshift and hunt a few times, and the rpms keep rising. No thanks, I'll take my slow revving ten that does not hunt on hills over a quick revver anyday.
