This is my build thread for my 2003 Ford Super Duty F-350 with the 6.0L. I am swapping in a 5.9 12 Valve.
I have owned my truck for 10 years, and I still love it. It has been through a lot with me, and as she starting running rougher, I gave a lot of thought about what to do. I tossed around buying a new F-350, but OMG are the prices are insane. I looked at buying a used truck, but the price to value proposition, to me, wasn’t there. I think the Cummins swap is kind of hard to justify unless it’s just something you want, but I figured what the hell, it’s the cheapest approach (or was when I started, lol) and it will be (hopefully) fun and a challenge.
I have been ogling Super Duty/Cummins swaps for years, and have read through just about every build thread I could find on the ‘net. I actually picked up a p-pumped 12 valve in 2012 (while my truck was still running well), but I chickened out and sold it a few months later.
As for my 6.0, I loved the way it performed (when running properly). I was very happy with the stock performance of the truck. My 6.0 has been mostly trouble free other than a FICM issue I fixed myself. It has never started well since I have owned it. It runs like crap until it is warm (no power, smokes, etc), and in the last couple of years it has had hard start issues. The hard start issues progressively got so bad that once cold started, I could not shut the truck off and get it start again. Obviously, I had an HPOP leak/issue.
After much agony and thought about what to do, I decided to swap the 6.0 for a Cummins
If I had to pick an awesome swap to model mine after, it would be Cut7’s. I think he did a great job on his build.
A few things about me:
I have never pulled an engine in my life, much less swapped one.
I do finance for a living, so everything I am doing I have learned from forums and youtube.
I am doing this swap by myself – no one to help, no friends with mechanical knowledge, lol..
My welds may look like something Ray Charles welded using his feet, lol, so please don’t be too rough on me. I bought a tig welder for this project, but have a lot of learning to do.
I am doing my swap in a two car garage, in a deed restricted neighborhood – no air tools. My truck fits in the garage with, no joke, a 1/4" clearance from the garage door (I actually had to remove the studs so the truck would fit).
Here is a pic of my truck:
Before my truck stopped running, I picked a low mile, 160hp VE Pumped 1993 5.9 12 Valve out of a wrecked truck.. I got everything with it, and I got to see it run in the wrecked truck:
I got it home, kinda thinking "what have I gotten myself into", lol:
It's gotta be clean! How do these engines get so disgusting??
Starting the tear down:
I had a leak on the top of the VE pump, so I decided to rebuild it:
And finally, the 6.0 threw in the towel after 228k miles. I know it's just an HPOP, but I am still on the side of the road. Luckily I was less than a mile from my house.
I hooked the strap up and am waiting for my bro-in-law with his 2015 Dodge 2500...
How fitting to get towed home by a Cummins, lol...
