Should I try to save a 260 Olds Diesel with 40,000 miles on it?

I am expecting the call in the next couple of weeks to bring my 79 Cutlass Calais in for the drivetrain swap. I am, of course, excited to finally get this done (6.0 LS (LQ9) & 4L80 for those that are curious) but I am not sure what to do with the current drivetrain. The 260 diesel is in solid running condition. I have driven the car back and forth to work, 40 miles each way, about a dozen times over the last 10 months. The car had ~39,500 miles on it when I got it, and now has just over 40,000. The transmission is the small hydramatic 3 speed, not sure if it is THM250 or 200. It has a floor shifter.

I hate to take a running engine and transmission and turn them into scrap or let them sit and rust, but there is certainly is not high demand for these units. I have no idea what to even ask for them, thus the reason I haven't posted on the classifieds. Are there any diesel guys (or gals) out there that would have interest in this ? Anyone know of another forum where I should post them ? The swap will take place in Alpharetta, GA, and I live near Augusta, GA. I've got a trailer and could transport within a reasonable distance.

Thanks for any advice, suggestions or interest.

Yeah, try and find a diesel message board and advertise it. The 260 diesel is super rare as they were either replaced with a 350 diesel or converted to 350 gas.

It'd probably make a good power plant for something stationary like a generator or pump.

Very cool engine, better design with the head bolts than the 350 diesel so they lasted longer. Unfortunately the bad press from the 350 diesel caused a lot of the 260 diesels to be either scrapped or swapped for a gas engine. I've got several of the Olds V8 diesels. I would say dont let it go to scrap for sure. Once they are gone they are gone

You are going to love the 6.0 /4L80 combination. It will be a vastly different experience from the diesel you now have.
No doubt. My first car was a 79 Calais with 305V8. When I decided to buy another 78-80 Cutlass, I knew that every engine offered back then was a detuned slug, so I didn't care what drivetrain it would have. I focused more on interior and body condition, and found this low mileage diesel. Still, it is a Calais model, so it has buckets and console, better power steering unit, front & rear sway bars, jounce bars, etc. That's pretty silly. 260 diesel, with "handling package.":LOL:

I would love to take that off your hands.

I have a build perfect for it. But I'm in NJ....
The swap will happen in Alpharetta, GA, north of Atlanta. I live near Augusta, GA. Shoot me a PM if you are interested. I'd rather see it get put to use than scrapped. Can probably include the fuel tank if it would fit your project.... and a diesel hood ornament 😁 I can't say for certain when the swap will happen, but we're hoping in February.
