Not positive but I believe I read that their 1000 lbs complete ( no trans ) . I have a lot of good memories driving around in a 455 ci
front wheel drive Olds . A good friend of mine ( still to this day ) use to drive his Dad's when we were in high school ( mid to late 70's ).
It was particularly good in the winter snow storms .

 

it's right about 1000lbs can't remember if thats with oil in it or not

 

Approx. 966 lbs w/ oil
Duramax is about 850 lbs
It's the Cummins that's the heaviest of the bunch at 1150 lbs

 

I'll accept the extra 116 lbs. not to have to drive an Isuzu.

 

Well sort-of an Izuzu. It's a joint venture between them and GM but it's made here, not Japan in a plant they both built

 

Semantics. Yes is made on U.S. soil but just how much GM engineering went into it and why did the mighty GM need to bring in Isuzu to build a diesel engine? Something they had been doing in large trucks for years. Oh yeah, almost forgot about that 350 diesel from the '80s. What did Chevy use in the '90s?

 

Semantics. ?

Whatever, I'm in Milwaukee, lotta guys I know work at Harley, ya wanna know how many Chinese parts are in those? Ya wanna know how many Chinese parts Ford uses? answer Lots.

get use to it

 

I will agree the Olds 350 Diesel was the biggest pile ever mass produced as a diesel. haha

But GM has had a pretty good track record using Isuzu for their diesel engine. All three makers leaned on diesel builders for their long track record of proven engines. Nobody competes with Cummins since they are in every train and all over the place. Great track record.
International had a great reputation until they pushed new technologies that were not proven. The biggest mistake they made honestly was tuning the 6.0 from original HP platform of 215HP to 325HP per Fords demands. They were competing with GM and their new DuraMax of coarse.
The tune pushed it beyond its designed output in all reality. Navistar figured that the 325HP was @ 85% of its mechanical ability. Then these hot rod tunes came along and tipped over the apple cart the rest of the way. lol Head gaskets bursting EGR coolers and HPO systems blowing out here and there. The swash plate HPOP would have been fine at a 215HP configuration. But not cranking out 3900 psi. I can go on but what's the point.

Anyway little at a time they altered the engine to be a reliable machine, just in time to release the next upgraded engine....6.4
Was nothing short of a nightmare in all honesty. The 6.4 was a bigger mess that Navistar never had the time to work out its issues. Think this all might have something to do with Ford kicking International out of their trucks............

Ok theres a bunch of crap there

 

I was saying you missed my point, not I yours. I also never said anything about not wanting to drive something from Japan or China. Though I do try to buy as many American made products as possible, they are fewer and father between now. That's something we can agree on. I'm not an Isuzu fan, sue me, but I have owned Hondas, Acuras, Nissans and Volkswagens. My point was why did GM need to use an engine largely designed by Isuzu when they had the resources to design and build their own. I'll tell you why. They were being beaten to death by Ford and Dodge (IH & Cummins) in the diesel market and were too scared or too lazy to try and do another in-house engine. I'm not trying to argue with you. I just expressed an opinion.

Why? because they owned a large percentage if Isizzu stock, that's why. The Japs also had a lot of time devoted to the design of this new engines fuel system, half the work was done. I don't prefer them, when I was a road service guy I drove one for over 100,000 miles, nice motor, more balls than my 7.3, quieter too

 

Okay buddy, whatever you say, but I'm pretty sure my feable mind did miss your point that time. I'm good with it if you'll just let this die. I'll even let you get in the last post. Go for it.

 

I'm 57 yrs old and drove GMC my whole life ( from 14 yrs old lol ) . About 10 yrs ago approx . it seemed like GM threw the
styling crew under the bus and hired teen aged girls from the valley to design their trucks . Wheels are round and wheel
wells should be also and as far as the rest of the truck , well enough said .
When all the dust settled on the 6.0 F series and the rite things done to it , it turns out that their a pretty good motor /
truck for everyday use . Relatively easy / cheaper to work on and decent mileage compared to others .
I won't be giving mine up anytime soon .
To the OP , I don't think you're going wrong here on your motor swap .
