so i bought my first diesel about 6 weeks ago. i picked up an 85 f-250 6.9 idi. its 4-wheel drive, its got the borg-warner t-19 4 speed, dana 70 rear with 3.54 gears, dana 44 in the front. ill post pics up soon. its the coolest vehicle ive owned so far in my life and my gf loves it. ill also post pics of the stack i just kinda whipped up it looks pretty good and itll smoke quite a bit when i want it too. i was actually suprised when i made it lug and rolled the coal. the best part is it gets about 18.5-20 mpg which rocks and as i write this im currently sitting in ocean city and i rode the girl the whole 187 miles down here. it rides like a mule due to the fact that the rear springs were re-done a few years ago with the replacements about as stiff as what you would find in an f-super duty . i hope to post pics soon.
