6.2 Detroit to 5.9 Cummins swap

I have a 1984 Chevy suburban with the original 6.2L detroit and the horrible transmission to go with it which is currently blown. The truck has Dana 1 ton axles front and rear. Which may get swapped with all this work im intending on doing. I want to pull the 6.2 and tranny and than remove all the wires, (lights, batteries, spark plugs pull the seats out basically get her down to a skeleton to rewire everything and clean it up..including sand paint the engine bay..having the motor pulled out will also give me a chance to get to the break booster/ master cylinder to have all the drums swapped to disc..lots of big plans wondering if anyone knows a good place to start any good suggestions..? or how bad is it to rewire all the lights and glow plugs..? I am familiar with wire.

There shouldnt be spark plugs. Has a hydroboost brake unit that runs off the ps pump. Not familiar with swapping in a Cummins so maybe check a cummins swap site this is the 6.2 detroit section. Good luck with your project lots of wiring diagrams and such in the faq for free download.

I did a Cummins swap a few years ago in a K30, there are a lot of things to think about.
Here are some links to swap sites, start reading.

It's already got front discs. Rear drums are fine. I have not found a rear disc swap that lives up to my standards. The big drums work pretty good back there. But you're sorta in the wrong spot for a 5.9 swap. Might want to check the swap sights, we usually keep the 6.2's on the road here

i have worked on many swaps. mostly gas v8 into rangers and pintos and crazy crap like that...but many types of diesel swaps and refits in commercial applications as well...going from cat to detroit back to cat ect...


but in this case, i am one more voice.... for this is not the place for cummins swap details. hard enough to keep on top of these 6.x critters.


but if i had a 3/4 ton or larger truck and i was wanting to tow with it. cummins all the way. or duramax.


i like the lug-nut 4x4 brake upgrades though. i have installed several and am ordering a setup for myself soon.

for wiring...the setups from speedway are real nice...the 22 circuit system is my favorite. lots of options and adding a extra block is usually not needed.

i think you can do it pretty quickly and cost effectively these days with so much data available....

i cant imagine having all this info back in the 80's and 90's....

I am tempted a few times a year to do a cummins swap. But my 6.5 is faster than my friends 5.9 in 95 with a few add ons. But if we are both towing he kills me
