They usually have steel camshaft gears, which is a plus.
I would use one, as they are made to last. Just compare water pumps and bolts when switching out, if you need to switch out the water pump.

When they say 'steel' crank they mean forged, and those are as good as gold in certain circles but extremely rare and hard to find. I doubt your industrial engines have one, but could be. Good luck. There is a thread on Fordsix about forged cranks. All Ford oe connecting rods for the 300 ARE forged.

Forged, that’s the word I was looking for ha. There’s a good Engine Masters episode of a buildup on an industrial six. Intake/exhaust/cam and some valve work really opens them up. Lots of little tips and tricks out there to pep it up. I think the beefed up cranks and exhaust only came in the medium duty trucks, but some industrials got them too. There’s an easy way to ID the cranks, but you’ll have to search for it, I can’t recall the marking. Never know what’s inside til you crack it open.

There are also a couple of episodes of "Engine Power" where they take one and beef it up.

I think the industrials also have a steel cam gear instead of the fiber/composite ones.

Don't order a w/pump from the efi years, 88-96, unless that is what you have. They used the serpentine belts and the pump spun in reverse of the V belt type pumps. I just replaced the thermostat in mine. I cheaped out a year ago and used the inexpensive O'reilley's name brand and it lasted a few months. Go with the MotorCraft brand. I had to surface my t.housing with sandpaper wrapped around a 2x4 to get it flat so it would seal. I also stuck the thermostat into its recessed area on the housing, and coasted the gasket with rubber cement. Then I stuck it on the housing and let it dry so it would hold the t.stat in place and not allow it to slip out when I mounted the housing. I always have trouble with it moving for some reason. The books says 198*, but that's up to you. Good luck.
