There's been a few of those swaps I've seen! There's a shop dedicated to that actually on TheTruckStop forum. Might wanna look into that. I forget the guys username tho. Sorry!
In the middle of a similar build struggling to get the right tach signal to the ez tcu controller? Tach says 600 tcu says 3000 what did ya do to get the correct signal from the alternator? Any help is much appreciated awesome build dude!
@geofflytwyn-th9nm I did this when I was 18/19, so that was nearly 10 years ago. I don't remember off the top of my head, but I would guesstimate to spend about 10k. 2k for adapter plate & hardware, 2k to 4k for a good running engine depending on supply/demand, and then another 2k to build up the 4l80e to handle power. The rest of the 4k is odds and ends. All the little stuff adds up quick. New radiator, New hoses, custom wiring, motor mounts were I think $800, to have the crossmember modified was a couple hundred bucks, to have the front core support modified was 1k. I have since replaced the 4l80e with an allison 2000, but the project has sat for about 4 years now due to other projects occupying my time. Good luck with your swap
@@Scholioso Yeah, thats about the range I thought it would be. Would I have to get the wiring harness from the dodge to be able to make it work? There is just so much unknown to me going from gas to diesel
@geofflytwyn-th9nm I'm not sure, but I would get the harness just incase. I did, and I ended up cutting the Dodge harness & making a hybrid dodge/6.5 harness. A lot of the sensors from the 6.5, I ended up just installing on the cummins motor. Then I had to extend or shorten the wires to each sensor has necessary. Only thing I really needed the Dodge harness for was the alternator and crank speed sensors. I'm utilizing the 6.5 ecm still. Not the Dodge ecm. These trucks don't care what engine is in it, just as long as the signals are in the right parameters. Which, diesel to diesel is similar. Gas to diesel however is another ballgame. Gas has an ignition system side of house too, diesel does not. It's purely compression/physics. Good luck with your project.
At this time, I was running the Screamin Seaman motor mounts (link below), and I don't remember the adapter plate company. The 4l80e blew up 10k miles later, roughly 3 times, so I inevitably gave up & pulled it. Been working on an allison swap since then. www.ssor.biz/

Hoy did you wire your transmission ? I’m doing the same set up and I have problems with my 4l80. I’m also using A quick 4 transmission controller thanks
I'm not running a Quick 4 controller. Hit up Joel Jones over at AdventureVehiclesNorthWest or their youtube joneseysautoclub. They have more info on those controllers
@stevenbean9706 not sure what you mean by mated tranny. If you mean the Dodge transmissions, sure, but then you have headaches with sensors talking to chevy electronics and different teeth readings and what not. Not all speed sensors are the same. Some read 32 teeth per full rotation, others read 33 per full rotation, etc. By using the same chevy transmission that was in the truck, I was able to keep all my electronics the same without modifying them heavily.
Dream build. Keep us updated! Would love to buy this.
Nice build, my dad has a 96 dually with a tired 6.5. I been thinking of this swap for a few years now.
If you keep the 4l80 in third and shift into d at about 60 it pulls a little better
I got a 1997 gmc 3500 454 long box crew cab and I’m deciding on if I should Cummins swap or Dmax swap my truck
ayy bro which intercooler, radiator, ac condenser are you running? i have a c3500 cummins with no intercooler just what your truck has
Can’t wait to install this Cummins in my humvee

Try going that fast with a 6.5 and 4:10s in the rear you would be picking up pieces of main bearing caps all over the highway
How did you get the tach signal to the tci tcu?
How are you getting around Cali emissions?
I believe older diesels are exempt from emissions in Cali. Which is funny
How did you get the tach to work right
@@donpatterson5294 If I remember correctly, I hooked up to the W wire of the alternator.
How much did it cost to do the swap? I would like to swap my 1993 c3500 to a cummins after the 350 gives out.

What adapter and mounts did you use. I’ve got the same exact truck and about to start. Trying to not spend an fortune lol

Did you have to change out the gas pedal to something like a '93 to run the Cummins?
@Nemo_IRL correct, I found a gas engine, cable operated throttle pedal and used that to run the throttle on the 12v
Sick I like kinda by you. Nice area! Did you have to body lift to fit anything?
Nope!
How did you complete this swap I have a 1994 Chevy Silverado 1500 6.5 turbo diesel wanting to swap a 12 vavle
1500 isn't a great idea, the factory small block is gonna be around 500-650lbs fully dressed, and a 5.9 is around 1400lbs from what I remember
How’s Tammy running these days?

So you jus plug stock wires harness?
@@thewhitebeast5815 No sir. I am running an EZ TCU controller.
How did you end up running your tach, from the alternator?
I connected the 6.5 tach "w" wire directly to the cummins alternator "w" terminal.
Instead of the 4l80 cant you just save a lot of aggravation and use a mated tranny right off ?
@stevenbean9706 not sure what you mean by mated tranny. If you mean the Dodge transmissions, sure, but then you have headaches with sensors talking to chevy electronics and different teeth readings and what not. Not all speed sensors are the same.

Something I wanna do
Does obtaining a Chevy obs 12 disel help you get the white ladies
