Decided to upgrade the work van from 2001 Ford E350 7.3 diesel to an 07 GMC Savannah diesel.

[Linked Image]

Had to drive it 400 miles home, it has way better suspension and ride than the ford van.

Of course you all want to know the MPG on the trip right? Well i had to go 400 miles down and back in same day so i was doing the full 80 mph speed limit whole time. It used 2/3 of a tank of diesel at a hand calculated average of 19.55. The ford would be lucky to get 17-18 at such high speeds.

A friend wanted the 7.3 van ever since i first got it, the tags were up, and this one was reasonable so i went for it. The duramax i believe is an LLY engine with no DPF or DEF emissions stuff.

Planning on keeping it on Rotella 15w40 as previous owner used. It starts up like instantly and is glass smooth. The 7.3 would really rumble compared to this.

Considering changing trans fluid (4L85E) to the new Dexron HP Mobil 1 equivalent that my 8 speed truck takes. Its supposed to be backwards compatible to the specified Dex VI for this year. I guess its just a little fancier and i happen to have a large stash of it on hand.

Thanks! I hope it holds up well as i really like the way it drives. Some guy on youtube has one cold starting with bad glow plugs and 652k miles he claims at least. Being derated down to 250hp probably helps them live a very long life.

I hope it gives you many years and miles....how in the world do they cram 7.3liters of engine into the front of a van?

That might be an LBZ engine? The 07 GMC 2500 Sierra Classic that I owned had the LBZ, great engine. EGR delete was the only thing talked about much, I never got around to it.

Only bad thing I've heard about them is the adapter plate between the transmission & engine, apparently they're prone to cracking. Solid otherwise.

Its still a 13 yr old truck for work. I would have thought people wanted newer trucks as work trucks since its their livelyhood.

We only use it maybe one day a week for obtaining goods. Certainly not like a traveling plumber or something like that. Or i would have snagged a like new Hertz cargo van with the 6.0 gas for dirt cheap.

They downrated because they not turbocharged. No room. No Allison trans either. Turbo 4L80E or newer.

That's not quite right, they downrated because of the 4L80E and I believe because there wasn't room for as large of an intercooler as on the trucks. The engine is definitely still turbocharged.

I used to loathe vans as a kid because my dad had one and I thought it was embarrassing. Now a few decades later.. nice van!

I can assure you it is very turbo charged and you can really feel the torque. While i was in mexico the van had no problem going from 70-95 mph in a hurry passing slower moving vehicles. I'm not sure if this one has an intercooler, the 7.3 powerstroke van was not intercooled.

Nice looking van. That's pretty unusual to find a diesel short wheelbase model, especially in a color other than white and with a sliding door. Any idea what it was used for before?
