Well maybe better said is the 400 is built stronger. If you are not going to work the truck hard a 350 weighs less and uses less power so it would be more economical to operate.
For a 3/4-ton four wheel drive I'd choose the 400 but its really a little more complicated than that...

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
