In 2010 when my 545 Allison gave up I looked high and low for a wrecked totaled Isuzu NQR 5.4L diesel truck. None to be found. At the time every wreck was snatch up and hauled off to Mexico and rebuilt.
Looked for wrecked Dodge Cummins w/automatic transmission. And again none to be found.
Looked for wrecked Duramax too with no luck.
I thought the Isuzu NQR would be the best swap. I even went to a truck dealer and measured engine to frame and it looked like the best fit, least weight, good torque, GW of the truck was 19,000 pounds. (AS-16500, toad-2600)
Not sure if it'd still true, but I found that the best information and parts are availability for the Cummins whether it's the 12v or 24v. You can put a P-pump on a 24v Cummins and then you can really go for the HP.

Thanks Brad.
I canít seem to open the link on my phone, so I will look when Iím on my pc.

Interesting stuff Mel.
Yes, there are a lot of engines that might work and I will try to document examples when I get info.
There is definitely lots of info on swapping Cummins motors into many different vehicles.
Since the 350/454 has been put in the C/K Chevy chassis a lot, Iím sure there is an engine mount system that is kinda plug and play.
I am not aware of any 24v Cummins Airstream conversions yet, but the block is the same as the 12v and the 24v head can be fitted, so Iím sure it would fit.
Then itís just a matter of integrating the electronics.

Just to add something that I found out in my conversation with JT5.9.

JT 5.9 did what I was planning on doing in the first place; he used a 1993-4 Dodge 2500 RWD drivetrain. Now the Cummins of that year was only 160hp with the automatic transmission as I'm sure Dodge was concerned for their transmissions longevity.

The 47RH RWD auto transmission differs from the later years 47RE, in the sense it was almost a manual lock out torque converter, where as the 47RE was fully electronic. The overdrive ratio for both transmissions is .69, which is quite tall. The problem with the overdrive was the tendency for the transmission to hunt between OD and 1:1; this took its toll on clutches and bearings. JT5.9 actually used a mechanical means to lock and unlock the OD from the drivers seat using a toggle switch. It was his reccomendation that bulletproofing the Dodge transmission would allow for an easier conversion and give the beast an overdrive, where as the Allison 4 sp is only 1:1 and would require a Gear Vendors.....which is pricey.

The benefits of the 47RH is that's it's tailstock overdrive is actually pretty well bulletproof in comparision to the 47RE and requires fewer expensive internal parts to bulletproof.

It is also significantly lighter than the Allison so I will save the Allison for my 5.9BT conversion on the Mistress, God forbid she needs it.

JT5.9 hopefully will send me pics of his install and show me how he managed to squeeze in an intercooler as well.

More to come
Cheers

One more thing...when I told JT5.9 that I've only paid $1150US each for both the Dodge truck and motorhome, he was flabbergasted with the low price. He told me the very powertrain, NOT including the rest of the truck will fetch $2,500 US in his neck of the woods.

So if you want a cheap Cummins and transmission, come to the Great White North.

Cheers

Yup, save on the unit and spend the difference on gallons or liters of Liquid Wrench breaking all the rusty bolts loose!

Actually, there is so little steel holding anything together, one good tug with the fork lift should seperate the body from the frame, cab and front end. That's what the guy doing the conversion does; use a reciprocating saw and a fork lift.

Sounds like my kind of wrenching!

This was me, some 12 years ago, removing some Alfa Romeo parts...
