dude diesel's are no joke man, they are monsters if opened up correctly. the horse power and torque is off the scales on these things today. my buddy bryan has a 2000 f-250 4 door long bed 4x4 with a power stroke and he is a full blown gasoline race car owner, but the truck is his daily, he started reading online about playing with diesel's a little and added a few power adders to his truck and for a plow truck/ tow rig for his race car, the truck will run high 13's in the quarter now, his mustang, with a big block and half the weight of the truck runs high 9's, so 13's in a pig of a truck like that is pretty sweet.
