Hah, no, 360K is the capacity of the floppy disks loaded on there The truck is barely broken in, driveline wise: I believe it's got around 150K on it from the maintenance logs it came with -- 5-digit odometer that's definitely been rolled over, but it was owned by a tree cutting company, then by a construction company, and both kept maintenance logs. The cab on the '85 is a little beat, but it's not quite falling off yet. I haven't decided if I should just let them run it until it does start to come off, and swap a cab on, or fix up the current one.
Those old IDIs are tough little engines though, especially since the 6.9 doesn't have as big of cavitation issues as the 7.3, so it matters less if the previous owner(s) weren't good on SCA maintenance. I know they don't have modern 3/4 ton truck power, but I've always felt like it was totally adequate for the job. I've thought about adding a Brownie aux transmission behind the T19 in the F-350 for overdrive, or better yet, double overdrive.
