5.9 because of simplicity, and haven't heard a lot of good things about the 6.7

I have had both. The 6.7 is a better motor IMO. There is nothing wrong with it.

Nothing wrong with the 5.9 either though.

i thought people said that the 6.7 camshaft is only supported on the ends, and if you tuen to many reps you can break it?

Never heard that. Some have had issues getting big RPM out of the 6.7...More tuning options on the 6.7, you could probably keep your minimax...I also hear a company in Utah will be releasing a 6.7 single turbo kit one day maybe.

actually looking online and 5.9 and 6.7 long blocks there doesn't seem to be a big price difference between the two, only about 700 more for a 6.7.... hmmmmmm

a 6.7 is just a little bigger 5.9. you could still control it with 5.9 electronics. Only difference is you might actually be able to find a clean, low mile 6.7 pull-out, whereas the newest 5.9 you'll find is 8yrs old now.

I'll go ahead and officially cast my vote for fixing the truck as a 6.4 vs. doing a Cummins swap. You'll be into the 6.4 build less than $10k hopefully, and if your ducks are in a row, you could have the truck back on the road in literaly DAYS. (buy a new short block from Ford, and get after it) You're going to be $20k+ into a clean 5.9 CR swap, and I predict that the truck won't be 100% ironed out/dialed in with all gauges working, trans shifting spot on, no lights on the dash, air conditioning, etc. by this time next year.

If you're just looking for a project, that's great, but I highly recommend scouring the various forums out there and reading up on how this swap typically goes down for those who attempt it. (I say attempt, because very few actually perform what I consider a "complete" conversion)

If it was me and would being doing a 6.7 1000%. It could be potentially less of a headache to do a same year swap from registration emissions etc.. In Wyoming prob won't matter.

looks to be the same kit from destroked either engine you use

you will want the 6.7 just simiply for displacement at this altitude, they spool turbos much better than 5.9s

Exactly

I just gotta find a place to get a long block from. Or get a wrecked truck. What is a good palce to get a block from, I saw black water engines come up on google and price didn't seem bad at all

I'd be a bit leary of any rebuilt motors unless it's a cummins "re con"

Stroked777 · Jan 11, 2015

Even if they have a 3yr warranty? I would rather o a remaned motor over transplanting one from a junk truck

From someone who has done a few conversions, this is the only way to go. Buy a complete truck take the parts you need and sell the rest. This little things here and there add up very quickly and waiting for parts adds a ton of time to the build.

My last swap was my Excursion and I bought a motor and found the rest of the parts online took forever and lost motivation half way thru. Now that its done I'm happy with it but finding parts sucks!!!!

Also like many have said look are resale, you might not think your going to sell it today but 3yr down the road when your having your first kid and want to get the wife into something safe. You might be selling your truck todo so.

Resale on Cummins conversions trucks is not great at all. They are usally worth half of what you have in them if your lucky.

Just my 2 cents
