Our 1986 K3500 12V Cummins Swap Runs!

Hell Yeah Brother 🇺🇸🦅

The first mod any 6.2/6.5 needs.

Looks killer bro! Donald should be permagrin each time he walks in the garage. The old 12v sounded so damn smooth, sounded like a sewing machine. Great work as always.

Love how the truck turned out, I would drive it in heartbeat. Your attention to detail is outstanding. Do what makes you happy keep it up.

I suppose the swap can be done in a weekend but tons of quality will be sacrificed, will leak oil and some certain things will probably need to be re-done after they have problems with the weekend job, quality work takes time and experience, well done Josh and Donald!!!

In the middle of a Cummins swap currently - putting a 24 valve in an 08 F350 ( had an emergency medical procedure slow me down - as soon as I get the aftermarket leg I’ll get back on it)!

Hell yeah, she sounds strong 👌💪

That's a badass old truck

Super clean, amazing work and you’re moving fast on it

You could definitely do that in a weekend. Couple guys big baggy of booger sugar to keep them going. 😂👍

Thank you for sharing love you helped save a square body!

No need being the cheapest. Do quality work for a fair price and you usually will always have more work than you can do. If people start saying what so and so will do it for I tell em take it to them. My labor is non negotiable. It costs what it costs and it takes what it takes to do the job.

Look forward to the updates. I also love that 12v startup where you know it is dead then it still continues to run!

Awesome series/build!!!!

Very nice swap, well done! As far as doing one in a weekend I call BS. We've got a mechanic lives nearby that everyone calls 8 ball, he damn sure could though. He once was working on a D6 that had slid off in a pond and he had the motor out of it half torn down and most of the wiring harness. This was after 5pm when I stopped by his shop to borrow some tools. I dropped them back off before work next morning and that Cat was being loaded onto a trailer!

Looks awesome!!!! I do this thing where I forget & leave my rag I wipe with acetone on the welding table & when I notice I'm always like woah that could have been bad. I see your whole jug on there and I think uh oh. I do mig sometimes so it matters more but be careful player.

Great work guys. 🥳

Turned out great! Attention to detail pays off, well done!

Just a really cool build, thanks for sharing 👍💯

I'd probably drive it. I like the 12v but I am going a different route. 1994 Chevy K3500, common rail 6.7, and a NV4500. I have been collecting parts for a while. Figured out the combination to get everything to bolt up nice and clean. Once I get the 07 mega cab out of my shop and sold the swap will begin. Bolting it in is the easy part. Making everything nice and clean is going to take time. I give myself a month to get it in and wired to move in and out of the shop. Probably a year before it's complete due to my work schedule.
