Hi CornwellToolMan - I was wondering if you can help me out. I've recently bought a C600 and am trying to figure out what chassis options I have for putting the cab on (I'm in the UK, truck is in the US, so I'll just be bringing the cab over here). Next time you're with your truck, could you possibly give me the width, height and length of the cab only please?
thanks in advance if you can help - will be following the progress on your truck with interest.
take it easy

Actually that was a olds based engine and they were fine after a few bugs were worked out, for the purpose they were designed for -
IE same 100k lifespan as a gasoline engine, they were never built as a 200k or more diesel, just a $400 option over a gas engine to get much better fuel economy. 32 mpg in a full size station wagon is not bad
However, people and salesmen saw "diesel" and assumed long life, Not so, $400 even in 1978 - 1985 did not buy much of a diesel!
Just some thoughts, having had several of them in various GM cars, and having pretty good luck with what they were, and accepting that as a base line.
Sorta like driving my 330 powered C600, it is what is it, slow and that is fine. Can't make it go any faster by any appreciable amount of money spent with the engine it was sold with, same with those diesels, they were what there were, same life span as a gas, with better MPG, and not at much more cost

The "Olds Diesel" was based on the Olds 350 but was a different block, crank etc. The details follow. 30 mpg under the right circumstances but otherwise a failure for reasons given here:
350 Olds Diesel | 5.7L Oldsmobile Diesel Specs & History
The "V8-6-4" is unrelated. It was a Cadillac gas engine and the valve workings and controls were developed by Eaton. I had read at one time that Ford had rejected this system. The computer controls were too slow, the fuel injection not sophisticated enough, and a host of other issues caused it to be a very short-lived engine system.
Current mds systems bear little resemblence to the clunky V8-6-4 system.

The 4-6-8 also used a 4 bit computer which simply was too slow to react to changes, Cylinder deactivation with the current computer systems works quite well, but it just took more computer power than was available back then.
Another case of being way ahead of the then available technology. But the idea was very sound.
Interesting read on the diesel, a few mistakes. The TTY head bolts did not come out until the later models, and they fixed head bolt problems, they did not cause issues.
32 or more mpg was normal in a passenger car with the 4 speed o/d auto, 28 with three speed auto (1:1 top gear) was normal. 38 mpg in the front wheel drive ciera's with the V-6.
This is from direct experience with several of these cars. (three olds 98's, 2 wagons (88 based), all with 5.7 V-8's, 2 ciera's (V-6's)
The short main bolts had nothing to do with the V8 versions, only the V6, and that was also due to the windowed main webs. Lower end failures on the V6 happened / could happen around 100 - 120 k miles, but that is within the designed life of a gas engine, and it was also within the designed life of the olds diesels.
Nuff said, sorry to see such a potentially good article be a bit short on exact details though, people will read it and assume things that just were not the case, nor be truly filled in what was truly the intended design of that particular diesel.... People took no time to educate themselves on what it truly was meant to do and be.....

8.2 "FUEL PINCHER" reliability of a 4cycle diesel with the same fuel system as the 2stroke detroits. what a piece of junk!
they were scary to work on in a school bus chassis. almost as tight as the Cat 3208 in the C8000s.
why not a reliable 7.3 powerstroke in it?
here in Ontario the 6.8V10 wasn't a big seller, rarely see one at all other than in E450 motorhome chassis'
nice project truck, build for short people to drive.

gas vs diesel operating cost for what I do with it gas comes out on top when you figure in maintenance and repairs
