Diesel 67-72 pickups? are there any?
Hey everyone. I am curious whether there was any factory diesel GMC or Chevrolet pickups. I have heard rumors that there were some fitted with either 3-71's or 4-53 Detroit engines. I know GMC had the V-6 Toro Flow diesels. If anyone knows about these I would love to hear about them and see pix if possible.
My goal someday is to put a 12 valve Cummins in a 69-72 4x4 suburban using the engine and drive train from a 92-93 Dodge pickup. That way i get heavy suspension, Dana 60 front end, 70 rear end with 3.55 gears and all the needed components for the engine conversion, ie radiator, ac stuff, wiring. I think it would be a pretty easy thing to do, just taking time and money. Thanks for any info. Jake |

Re: Diesel 67-72 pickups? are there any?
Duck, this generally opens up a can of worms. There have been people shot in pistols-at-50-paces kinds of duals around here over what the best diesel is, and whether or not you should put one in a 67-72...
Its been done, though. You might try running a search for the word "diesel." Search function is 3rd button from the right at top of page. BTW, welcome to the board!!

Re: Diesel 67-72 pickups? are there any?
On your original question about factory light truck diesels.I think there were.In the thousands of trucks I`ve seen in two centuries(a bit of an exaggeration),I`ve never seen or known of one.But,in the 46-72 Series 10-30 parts book there are parts listed for truck w/diesel.There were propane trucks offered for a fact.I`ve never seen one of those,either.
I`ve been invvolved in the defense of 6.2/6.5 GM diesels when they`ve been called boat anchors,since I`ve gotten alot of trouble-free use for nearly 20 years out of them(no exaggeration).Although "I" believe the Cummins I-6 is hands-down the best light truck diesel out there,I have argued that it`s not the "easiest" to convert.I read the text and answer according to what the question is.The arguement has often been when someone asks what`s the "easiest" diesel conversion to perform and the replies answer what is the ultimate "best" conversion.Not always the objective for some.When it comes to simply try to save monwy on fuel,saving money on achieving that goal is important,that`s all.Someday,you "will" see me driving a Cummins-poqwered vintage GM.

Re: Diesel 67-72 pickups? are there any?
See...no enemies here.It`s all good.
That`s a tough one.I haven`t run into that one.I know they need(all diesels)torquey starters to turn the compression.It`s prolly hard to beef-up there and welding is near impossible on oily old cast(and,engine in truck over your head).I`m thinking a brace to the frame,but it would need to flex.I`ll check around.I`m not registered on www.thedieselpage.com anymore,so I can`t post the question.But,maybe a search will pull it up.

May have been Detroits, because they(Especially the 283 6-71's) have a huge following..........But I imagine it was 350 Diesels in the early stages. Way he talked they were factory(Well they came from there anyhow), and if they put it in at the dealer I am sure my grandfather would have remembered it. I miss Howard, I was looking forward to getting him into my C-20 with the Cummins..........I know he'd have said this is how GM should have got into the light truck/diesel scene.

I have never seen a 67-72 with a factory diesel, but that doesn't mean it didn't happen. Go to the second truck on this page. http://www.6066gmcguy.org/V6powered.htm

Re: Diesel 67-72 pickups? are there any?
Did GM do like alot of farm equipment makers did back in the '60's and 70's............They'd take a tractor for example, off the line.........Move it to a special department and by hand, install a different engine(Not radically different, small stuff like bigger injection pumps and increased bores and stokes.........larger turbo's etc....... They'd then truck it to a larger dealer and let the dealer place it with a good customer to use and they'd track the progress. After a period dealer would get it back and truck it back to the company and they'd inspect it..........Notes were taken and it was either put back the way it was tested or put back to stock........Then sold again. IH didn't do much of this as they had their own test farm like Deere, but I know alot of storys about Oliver(Later White) doing such things. GM do testing on its own grounds? Or elsewhere like this?
When old Howard told me this, he mentioned the railroads.........Don't know if they bought them, or were doing such a test? Such a thing sound logical?

Re: Diesel 67-72 pickups? are there any?
I have heard that a small number of GMC prototypes were built in '67 and '68 with the Toroflow V-6. I doubt any of these were ever sold to the public, but since the Toroflow was based on the GMC V-6, some swaps were done. The '67 and '68 shop manuals and parts books have listings for diesels in light trucks, but these were Detroit 3-53's that were RPO's in P-2500 and P-3500 Step Van chassis. For the record, Dodge built a few 3/4 ton pickups with Perkins diesels in the mid-60's. The Perkins was a special order option primarily for export, but it seems that a few were sold here.

Re: Diesel 67-72 pickups? are there any?
I remember the n/a Perkins being a flash-in-the-pan in the late`70s,around`78 or`79 I believe.It was about the same time GM started their 350 diesels.

Re: Diesel 67-72 pickups? are there any?
Actually, the diesel that Dodge offered in '78 and '79 in the pickups was a Mitsubishi. 6 cylinder, no turbo. Very durable, but only something like 120 h.p..
