Anyone here done one? My 5.9 Magnum is a little tired and will need some serious attention in the not too distant future. Rather than rebuild the Magnum and likely still get crummy economy, I was considering a 3.9 Cummins 4BT. It's a 4 cylinder turbo diesel most commonly found in bread trucks. They are one of the most popular diesel swaps out there but I have not seen one in a dodge van. There is a Ford E-series van on youtube with the 4bt swap. Its been put in about everything else, just haven't seen one in a Dodge Van. It is quite a bit heavier than the 5.9 magnum but I have the Heavy Duty 4000 lb front end so that shouldn't be an issue. I found an auction for some industrial equipment that has 2 Dorito trucks with 4BT backed by an Allison 1100 transmission the initial bid is at $250.
The main goal of the swap would be economy. The Workhorse Vans (bread trucks) are rated for 25mpg! I have also toyed around with the idea of burning WVO. There's a Chinese restaurant within walking distance from my house that I could source it from. Besides all that, the Cummins are super reliable. My father bought one new in his 89 Ram truck. It has over 300k now and runs just as strong as the day it rolled off the showroom floor. Last but certainly not least, NO more changing sparkplugs!!! LOL
What do yall think? Tips, advice, recommendations welcome.

I think it would be a great swap if you can pull it off. Dodge B series vans never had a diesel option, so you would have a lot of fabrication ahead of you. Fortunately, there are a large number of parts that interchange with the D series trucks, so it wouldn't be completely from scratch.
Windows- they're what make a van worth owning!

The mounts would need fabbed for sure. Need something extra cushy to help absorb the vibrations they are known for. Brackets for the a/c, p/s, and other accessories too if they don't fit as is. They share all their parts with the 5.9 6 cyl Cummins so brackets can be sourced from there as well. Size wise it should fit since it is a 4 cylinder. Does anyone have the dimentions for the 5.9 magnum?
I remember that there's a Fuso box truck that used the a727 transmission, so some people have theorized that its diesel would be simpler to utilize because the stock small block a727 would bolt to it no problem, but all the details have left my memory... Which engine it was, or if it was any easier to mount in reality, all gone.
