What are the specs on my rust bucket truck?

Question

I have a 1989 Ford F-250 Custom Diesel. I know it is a 7.3 liter, but I don't know if it is a navistar or a powerstroke. Or it could be something completely different. Please Help!

Answer 1

Navistar

"1988 also saw the replacement of the 6.9 L (420 CID) diesel V8 with a 7.3 L (445 CID) International Harvester IDI diesel V8 (now making 180 hp (130 kW). and 365 ft·lbf (495 N·m). of torque)."
