Hemi to cummins swap

So ive been toying with the idea for some time now since I love everything about my truck except that its not a diesel. Ive done a little research and it can be done but as long as its a similar truck to avoid the most headaches. I am really thinking about it now since I found this truck locally and its pretty much exactly identical as mine except for the engine.

2003 Dodge Ram

So my questions are how hard would the swap be if I got this truck and is the price they are asking a good price for a truck in that condition?
Thanks for any input

it would be way easier to sell your truck and buy a cummins. i dont think i have ever found anyone who has swapped a hemi or 4.7 from a 1500 to a cummins in a 1500. it would be sweet dont get me wrong but it would be basically pulling a whole 2500 cummins front end and welding it onto a 1500 hemi/4.7 front end along with swapping all the modules, all the wiring and all the linkages. hope this helps and anyone else that comments back feel free to correct me.

It sounds to me like it wouldn't be very cost effective. IMHO

butcher, first of all my truck is a 2500 hemi look at my sig lol, so it wouldnt been near that difficult but i guess not as cool as a cummins in a half ton 3rd gen either haha

carl, ya thats what i was thinking to that alot for what i get but then ive also put around 3k into my truck this past year with tires and parts so kinda dont want to get rid it of either. my plan would be to since the doner truck isnt that bad swap the hemi back into it if i could and make it a f*ck around with 4x4 pretty much. would be ALOT of work for both trucks but since there both complete and the exact same truck pretty much should just be mostly wrench time

Hmmmm...I wonder if the front springs and suspension/spindles is different cause of the heavier engine? You might be switching whole front ends as well.

No way, no how, would'nt do it. In my former life as an automotive mechanic, I performed engine swaps, and even with detailed planning there were always surprises that complicated the project and increased the cost. These were also much simpler gas for gas swaps. Two small examples: Does your gauge cluster even have the indicator light for the glow plugs and if it is the same cluster as diesel, is all the wiring there for it? Think of all the changes that will be necessary to the fuel delivery system alone. If your not bothered by the enormity of the project, more power to you! But I think "Butcher247" is right, you'd be money ahead to just look for replacement with a Cummins.

Sorry, my mistake, I guess I spent to much time dealing with those worthless glow plugs. Heat plate, heat plate, heat plate. Thank you Cummins for the heat plate.
