My 1990 f250 has 161,000. The 1984 F350 I just scrapped last month, had 413,000 on the 6.9 diesel with 1 clutch, 1 radiator, 1 injector pump, 2 supply pumps,2 sets of glowplugs, 1 starter, and 2 water pumps. Not bad for a ford, finally scrapped it because the body condition was not worth the $ for transmission repair and new brakes...
