gas or deisel?

ok which would be better for reliability,econamy,and power? a 7.3l or a 6.8l gas? which would be better fro trails to? thanks

I would take a 7.3 Power Stroke over anything except a 4.9L I-6.

the 7.3 liter offers more torque but if you are going to be offroading the 6.8 offers higher rpm's. for getting through the mud. But nothin sounds quite as good as a diesel roarin down the trail

i have the 02 F250 7.3L and love it!
