1991 Ford IDI engines/trucks for towing
I have an opportunity to get a 1991 F-350 SRW IDI truck, it is in good shape and I have some extra money to spend on fixing it up. How are these for towing? I own a 2016 F-250 6.7L Ford and I alrea...

First off, I've found STEEP 25+% grades here in Seattle at basically sea level. Freeways ie interstates are legally per federal law limited to 6%,with short stretches to 8%.
It has as I noted half or less of the HP/torque of a 2915 or so any brand diesel. This motor was a farm truck staple, school bus for many years doing things at speeds to 40-60 mph.yes it will pull up to mid 20,000 gvw/gcw pretty well in my truck to around 50-55. It can do 60 on a level, in my case that is about 134-150hp from doing some figuring. I also have a computer print out from a dealer showing that to ba about maxed out. Most motors averaged about 100,000 miles doing the kind of work it did. A friend of mine doing lawn spray apps, would rebuild at 5000hrs, or 40'ish thousand miles. He did a lot of idling running pumps. He went by hrs more than miles.
I have around 150k.had heads redone. No other major work yet.....
If it leaks around injectors. A $5 o ring kit will solve that. Put new typical fuel rubber hose and close at the same time. $25 maybe total. I did a few weeks ago. My first time personally doing. Very sole. While at it, change glow plugs. As two need fuel line loosened and remove.
Glow plugs box and wires are semi known issues too. Easy to do.
As are injectors. If you've wrenched gas motors from that time frame, or pre 72 emissions motors. About that open and simple
Power wise. Because of the high compression, off the line I've heard a few say it's better powered initially than t444. Once turbo spools up no comparison.
You will probably find yourself in 4lo a lot pulling off road, I do well with just a red. But I have a 45-1 overall low in first gear. Most pickups even with the typical 4spd auto at that time are around 25-1, auto mid teens to one. Hence why I choose the 7spd vs 5 or 6 so manual, or 4 sp direct drive Allison. All trans options were direct drive in the IHC models.
