do you listen to your old alabama tapes in your tow rig on the way to go wheeling? Do you love your old manual fummins? Do you need more room for fat chicks and your dog? Do you need a hp60 to build a new axle for the front of your buggy when you go rear steer? Do you want to be able to go over 65mph? Do you want ac? Did you just finish your buggy and find yourself bored between wheeling trips? Well maybe this builds for you!

It started when I decided to take a 6month wheeling trip at the end of my current three year project and i started looking for a cclb obs to put the 12v i swapped into my 89 single cab f350. After looking at a few most were beat but I stumbled on a loaded 08 cclb superduty black leather all a fella wanted for a screamin deal with a blown 6.4L. But heres the issue it’s auto. Yuck. So here the solution. This truck will be 100% manual as far as drivetrain goes….

I will be sacrificing the 89 f350 unfortunately but most good parts will be used. The build as of now is planned to go something like this…
08 F250
-96 p-pump cummins
-89 ford f350 zf5
-ford np205 with jb fab twin sticks
-zf6 master/ zf5 slave
-dcs adapter plate
-stripped harness
-mike fuks motor mounts and accessorie mounts
-35’s leveled on methods
Now for some pre build pics…

Can’t wait to follow this. The 6.4 trucks are great candidates for a 5.9. I’ve even started to see 6.7 cummins get swapped in to them.
 
Well nv4500 were pretty well touted but just dont really seem to be the brutes they were once thought to be.

A 12v and a psd frankly are completely different animals. The trq put down seem to be significantly different.

I have a ZF 5 for the 12V conversion I renigged on. I’m less concerned about the ZF having issues than I am the NV 4500 issues.
 
I’ll be watching. I have to say a new paint job and maybe new interior on the 89’ would be more to my liking, but this will still be good. I suppose there won’t be a cassette deck.

Well atleast hes not renigging on the 12v like the last guy that bought a pos motored ford.......

Curious on opinions of the zf5 holding up to a 12v from op and the peanut gallery.

Only ZF experience I have is with a ZF6, GM version. It got replaced once and rebuilt twice in less than a couple thousand miles before I sold it. Don't know what major differences (other than the gear count :homer:) between a ZF5 and ZF6 so unsure how relevant that is
 
Cool build :smokin: I really like the idea of finding a later model truck with a blown engine and putting a mechanical diesel back in. I have seen a few builds that were so clean, they looked like they came from the factory that way.

How much power are you planning on, and is the tranny an S5-42 or an S5-47? The diesel 47 version has better gearing in my opinion and a 50 Lbft higher torque rating from the factory (although I don't know the details on what all is actually different). I have seen posts from some of the performance IDI/7.3LPS crowd that make me question using one with 800+ LbFt, but other than that, they seem to be pretty stout trannies and better than the NV4500s.

They are more expensive, harder to find and have a somewhat odd-ball 34 spline output, but I am a big fan of the S6-650/750 that came in the Superduties. Strongest manual transmission ever put in light duty trucks and tighter gear spacing than the 5 speeds. I am not sure what is different in the GM version, but I know it had a lower GCVWR than the Ford versions. I am not sure how an NV5600 compares, but my impression is that they are quite a bit better than the Mercedes G56 Dodge used for the majority of the run behind the common rail engines.

That's hilarious, I want to do the opposite.
I can't stand all the plastic and shit from the newer vehicles, but the new engines/trans are awesome

I’m not a fan of common rails just for the required electronics. Hard to complain with the power they come with though.

I just want a harrop blown Godzilla and the 10 speed in some old iron.
I'm slowly making peace with the idea that if I ever need to tow heavy I'll get a HDT and avoid 1 ton diesel vehicles altogether
 
This will be sweet.

Working on [Ford] 6.4's and 6.7's SUCKS DONKEY BALLS, but a 12v in there will be awesome. And there are more than enough 2nd Gen Super Duties out there to find parts.

Will you run into any issues with the length of the engine? Fan/radiator clearance?

I get that. I definitely like the styling and interiors of '60s-'70s trucks a lot better, but it is hard to argue with the comfort, refinement, and capability the new trucks have over old trucks. I wouldn't swap an old school gasser in a modern truck, but the new diesels are so expensive, complicated, and hard to work on that I think swapping an old school diesel in one makes sense if you live in a free-er state. Obviously you lose some of the comfort and refinement the newer truck provides doing that, but it is still an appealing concept to me.
Along those same lines, there is no way I would buy a new diesel over a gas truck. Even in the used market, I would have a hard time convincing myself to buy a post-emissions era diesel and dealing with all the headache deleting one entails.

I have to do a HVAC refresh in my plastic dash truck. I dread this shit.

Anything plastic can fuck right off

I don't need comfort, I drive a non-AC, crank windows 300k miles work truck and have been all over the lower 48 with it.

I think the Superduty is the easiest truck to swap a Cummins into. A 5.9 is tiny compared to all the nightmare that is a 6.4 under the hood. I tried to buy a 6.7 Cummins swapped king ranch from a guy on the old place that looked like a factory truck. It was completed by a shop and everything worked. A/C, cruise etc. the 6.7 fit like it was made for it even with the engine driven fan using the factory ford radiator and ford intercooler.

I am/was of the same mind set, but I am starting to come around :laughing:

My current tow rig is a 2000 7.3L, which was a huge upgrade over my '84 6.9L since it has working air conditioning, cruise control, power windows/locks, and is a little bit quieter at interstate speeds.

After riding around in my cousin's old 2020 F350 with the 6.7L 10 speed combo, I am starting to think about getting a nicer truck some day. It definietely makes the long-haul trips a lot more pleasant riding smooth and not listening to the 7.3L cackle/clatter for hours on end, and it towed 20,000+Lbs better than my truck tows 7,000Lbs.

I edited my post to clarify that I think Ford 6.4s and 6.7s are the shitty things to work on...

But it's rad to hear that everything fits well. A Fummins really seems to be the best of all worlds.

Should be a sweet rig when it's done.

What're you doing with the rest of the '89 F350?

Its getting parted out i already sold my service box it’s got a mint interior but its just not the truck i want the front axles getting used to build a hp pass drop 60 for the front of my buggy and my lp is going in the rear.

It’s a 7.3 diesel zf5 it’s been in my fummins almost two years with zero issues towing all the time. Ive had lots of cummins trucks 89,94,98.5,01, and an 04 all manual trucks. I only had issues with the nv4500 trucks so ill never go that route again. If i could find a nv5600 id go that route. But i have everything to make the zf5 work so thats what ima roll with especially since i dont plan on pushing over 400hp just reliability is what im after
