This is my '89 F-350 Centurion Conversion. It only had 79,000 miles on it back in '96 when I bought it, just turned 300,000 miles a couple of months ago. I have driven it from coast to coast too many times to count and have only had one major problem, I blew the oil rings out of 3 cylinders and had to put a new longblock in. Should be good for another 296,000 miles. :)
New 460 longblock assembly, K&N Filtercharger, Doug Thorly Headers, Dual Optimas, 200 amp alt,Pioneer CD head unit/12 disc changer, 3 amp=2400 watts, 4 10" sub's, Infinity component speakers. New GT 500 hood and repaint coming soon!
