I have a neighbor that has a 3 cylinder diesel motor in an old power wagon. It's pretty sweet other than he's kind of rednecky. It's always dirty and he carries junk in it all the time. With his big dog in it.

I thought GM's experiments with using gas blocks for diesels ended before the 6.5 came out. IIRC the 6.2 was not a gas block as well. The gas blocks were used in the cars which were nothing but trouble, but I may be wrong.

chevrolet and oldsmobile both sold the 350 diesel, basically a 350 gasser converted. 6 or 7 quart oil pan, different heads and induction..... My aunt had one for yearsin a full size oldmobile station wagon...... Drove that thing everywhere, guessing 150-200k miles, sold it to another person I know, he blew it up in about 2500 miles,,, changed the oil put 5 qt in and did not pull the stick.

He said ford and chevy were converted and that the cummins was a true diesel because it is a six cylinder and that diesels were six cylinder. The guy is an automotive mechanic that I have been knowing for 29years but I don't believe half of what he says. I was wondering if what he is saying is true. I didn't think it was a converted diesel.
Rumor has it that the 6.9 was slightly based on a perkins industrial motor... however, that has never been proven. Looks from the outside are similar, but thats it. The person who said that the I-6 ***-a-part is a *real* diesel because of the inline configuration must not count diesel locomotives as real because they are V style... Some people...
Hey, I've seen quite a few Scout II's, and even a Travelall once, though it's kinda rare to see one scootin around.

Some automotive mechanics know nothing about diesels. What you just told us is proof this guy doesn't know what he is talking about.
I just went and played on some locomotives on Saturday. One of them in particular, had two 12-cyl diesel motors (along with a GIANT blower that was pretty sweet!) Anyway *sidetracking, sorry* ....just another piece of information to consider.

Brother in law had one of those old 6.2's in a Suburban. What a piece of crap. According to him, you can make those motors reliable but they basically need a lot of overhaul. You can read about those conversion motors in a lot of the diesel magazines.

The powerstroke was actually designed using technology that CAT helped to pioneer, HEUI (Hydraulically actuated, Electronically controlled, Unitized, Injectors) Cat and International share this technology
The 7.3 Powerstoke, and the Cummins 5.9 are the only two Medium Duty diesel engines that were avail from 94 till 03. the 6.6 duramax was classified as a light duty diesel when it was introduced in 2000, as well as the 6.0 PSD that debuted in 03. the 5.9 Cummins was avail till late 07.
Hundreds of thousands of school buses, panel vans, garbage trucks, and city service trucks cant be wrong, nor would they still be running on converted gas motors.

The 5.7 was a gas motor converted. They mainly put them in cars not in pickups. The 6.2 was a diesel from the start but it had some weak points. The 6.5 was completely different from the 6.2.

Thanks, That is what I thought, but was not sure. The 6.2 was actually fine as a run around in the half tons. I know several that are still going with who knows how many miles on them.

The reason Ford went for the V-8 was 2 fold--First, a V-8 diesel would still deliver low end torque but also operate in a wider RPM range than I-6 engines of the day, and second, it was an easy fit for their pickups chassis that were already designed around the V-8.
The story about the 7.3 being a converted gas engine probably had it's beginning in the fact that International did build a similar displacement gas engine. The 6.9, 7.3, and 7.3 powerstroke were all designed as diesels.
The 7.3 is based on a gas v-8 about as much as the Cummins B is based on a Ford 300 I-6.

I had two rigs with the 6.2. Both had close to 300k when I sold them, and always got 20-25 mpg. I do have a 98 Suburban with the 6.5 diesel and I hate it. It has good power but mpgs are only 14-18, more often 14 mpg. It also cracked both heads when towing, the electronic fuel system stinks, and many other issues. I can't wait to sell it and get an Excursion.

I here ya on the 6.5. Seem to have power, but work them hard and they break. Hope you can get an X. We love ours with the psd in it. My wife says she cant imagine driving anything else.
