05 1500 ram 6.7 swap!

Ok I have a 2005 Dodge Ram 3.7 v6 that I got with blown headgaskets I don't plan to fix. Since dodge frames are full box semi rolled corners there is more than enough strength to play with there. The motor is a 2015 6.7 from a 3500 ram. I am aware of the fuel rail sensor being different than the 7.5-9 style and have to change it anyway since it broke on removal. The rest of the sensors are the same I have spent more than a few hours looking into this before continuing. I emailed diesel conversions and they said they can't cover the 15 year wiring due to electrical differences not sure why but hey I can do it myself. I have 7.5-9 pcm pigtails coming from a dealer buddy and if that can't be had brand new engine harness will be the way I go either way I am switching to the older harness. I will be getting a 7.5-9 pcm and a tuner from someone that can help (ideas/referrals here needed). I already have a diesel 727 with a gear vendors OD unit on it. The engine will have no emmisions crap attached to it at all either. The motor will be stock won't need HP in 4K less weight truck lol. This should be an interesting little setup once done it's one of those swaps you always see online and read about but never actually see anywhere in person I am finally going to do my own!

This is the trans I will be using for the swap. 727,converter,gear vendors,flex plate and adapter for a cummins. All brand new never used. This setup has no lockup and will mainly be street driven with a little track racing. For now I will be using the 9.25" diff bit have a ford 9" behind the barn I will be rebuilding to go under the truck after I get it running and driving.

Third gen radiator and intercooler for a cummins I just scored for free! Buddy was doing a swap of a 24v into f350 and ended up moving sold the truck and motor but kept these two. He told me take or they are trash so I did! Getting closer every day now.

Also I am changing it up a touch and going with the 2006 5.9 pcm custom flashed to get me going on a stock non security file just power up and start motor. The harness will need a little modding but that's the easy part. I will post pics as I get things going. Tomm getting crank out and making sure engine is good to go with a touch of machining.

Finally got her all torn down! Three rods took damage to the bearings nothing spun thank god but crank will have to be turned down on three journals and oversized bearings installed in it. The rest of engine is good to go need to clean it all out and ride. Going to be a touch while I get crank sent out and machine work done.

Just a point on running the cm849 ecm rather than the cm2100 like you were planning, you’re going to need to switch to 5.9 injectors as the 6.7 ones fire with a different voltage, and it’s very hit or miss whether the guy hitting the keys on the tune will be able to get it to run decent/at all (even the best tuners aren’t exempt from this).

What is the firing voltage on the injectors I have read this more than once and I work on these trucks and everything I read says they are about the same. I was planning on running 50 tips maybe to add in a little fuel as the 5.9 pcm is going to pulse a little different than the 6.7 computer would so fuel might be off a touch. I was at least going to try it and see worst case I swap injectors and tips!

Ok well builds like this swing a lot. I am going 2006 pcm now with a painless wiring harness to eliminate any possible wiring issues. PELA will be tuning as they are just down the road from me. Block and oil pan dry fit will be happening very soon!
