T444E or Does PowerStroke?

I have my eye on a 1998 Ford E450 shuttle bus...the engine model is not specifically listed anywhere that I could find, but I did find a sticker that says "Navistar 7.3"

As best I can figure, the most likely candidate is a T444E, but I know Ford had a similar 7.3 PowerStroke that they used in their pickups.

If it's the Ford version, would it say Navistar? Or because it's a bus, would the Navistar version be used because it's more "industria-strengthl"? Or does it not really matter?

I don't have a ton of experience with these engines, so any input is appreciated!

AFAIK they're basically the same engine block but PowerStroke is a Ford trademark. Some of the add-ons are different because PowerStrokes are marketed in consumer vehicles while Navistar is a commercial vehicle application.

Thanks! That's kind of what I was thinking. Nice to get some independent confirmation though.

A 444E won't be found in a van. That would be a 7.3 powerstroke. They're the same, but different. lol

Seems weird then that it would be labeled as a Navistar...

These aren't the PowerStrokes that everyone complains about though right?

No, that would be the 6.0h-no... Navistar's VT365 under Ford's marketing name, as someone else mentioned. The 7.3 PowerStroke is a modified Navistar 7.3 / T444, other members here have enlightened me to the fact the Ford-marketed version has some differences to allow higher rpm range under load. T is turbocharged, E is electronic control.

The 7.3 / T444(E) is good stuff, the 6.0 / VT365 is the one you want to avoid (03+ up, though some '03 E350s snuck out of the factory with 7.3s (I believe they may have been built this way to use the leftover engine supply from the '02 model year.

they say navistar because navistar built and sold the engines to ford.. the fords featured higher Top RPMs.. electric fuel pumps in later models, and more power than the T444E counterpart. the bottom half of the engines are the same.. the head gaskets are different, turbos are different, electronic computer controls are different. serpentine belt drive is different. flywheel housing is different.. as the ford accepts ford transmissions, where the IH accepts SAE transmissions.

Thanks for the excellent explanation!

All the possible engine/trans combinations make my head spin sometimes...

Thanks for clarifying that.

the combinations in the commercial world are endless.. even back in the 90s ordering a simple econoline Van had endless combinations when you ordered it from the commercial fleet ford dealer..



the incomplete chassis was even more complex.. yes even the right hand door was an option on an incomplete chassis.. as was a roof over the driver compartment..



a motorhome builder might order an E450 incomplete chassis with a roof and 2 doors, where a bus builder might order no roof and only a driver door..



the powerstroke in the van chassis was a bit different than the powerstroke in the F-series trucks.. (space constraints meant different turbo and up-pipes).. oh and in the Bigger F trucks (450,550) the trans housing was SAE and not ford.. ha! but wait the powerstroke 7.3 was never offered in the B-series school bus chassis.. but IH offered it in the 3800 school bus chassis as a T-444E...


oh and cant forget Mercury Bought the 7.3 and turned it into the M-444E Mercruiser Boat motor....


they ended up in quite a few of those amphibious 'Duck boats'
