Im intrested to know if anyone has fitted a duramax/allison combo into a 92-98 f-250 4wd? Most of the conversion guys here (in australia) dont want a part of it saying to many issues with adaptor plates.
Citing the drivetrain mounts on the transfer case are opposite sides,do i have to buy a suitable transfer case as well ?or as i have been reading on the forums on here would cummins be the way to go?
My truck spends 90% off road dirt roads,sand dunes flooded creeks,im after good torque and low down grunt!!
Any feedback appreciated

Okay, you asked for it...

Why, in gods name, would you ever, EVER! think about putting a damn chevy motor in a Ford! The car gods will strike you down and you will burn in total damnation forced to drive a Prius in the slow lane of hells highway for all eternity.

If you have to have an oil burner then you have much better options. The 7.3 PowerStroke was installed in these trucks and would be the only diesel I would ever own (though I'm a diehard gasser fan). The Cummings, according on which engine, is a popular swap that is well documented and is almost sorted out enough to be a bolt in.

Now being that I am a big block lover I'm going to suggest the 460. They are lighter than a diesel and can put out comparable power. True, a built 460 will make its horsepower a little higher in the RPM range but you don't have to wait on a turbo to spool up. That would be what you want when bombing down dirt roads or jumping over sand dunes. And the 460 is more that capable at giving globs of low end torque. It all depends on cam selection. A stock EFI 460 will give you great torque down low but it will be a little limited on the top end. If you need more then drop in a stroker crank. The 4.3" throw of a 514/521 will almost double the torque if built correctly. The only bad thing about a big block is the gas mileage. Stock EFI 460s get 8-12 according on how you drive it. Also, and this maybe the deal breaker for you, is when you're in the outback diesel maybe more available. If that's the case then I'd suggest you find yourself a PowerStroke truck. It would be a lot easier/cheaper to find a truck with an oil burner in it already than do any swap.

 

good feed back fellas,Jokr you on to it,totally agree about b/b's thing is like you say the distances i travel,we're talking of 1000 km + already carry 2 tanks 150lts roughly,that does me for about 900km not bad i reckon.
i throw a 44 gal drum on the back just in case.anyhow has to be a oil burner as gas is not a option in a lotta places,plus less hassle in river crossings etc.
Still its all food for thought before i get sent to the hwys of damnation in a prius if i change to a chevvy donk,but the accolades for a 6.6lt are out there

 

looks like the 6bt could win over the duramax

 

im pretty new to this computer stuff but have to say im impressed with this site and all the posts and advice,keep up the good work fellas.

 

So what are you driving now?

 

at the moment i own a 92 f250 4wd with the 7.3 naturaly aspirated navistar eng with 280,000 on it,hey a sound ole donk dont get me wrong she has ploughed through some hairy situations but seems to dislike soft sand even with the tyres down,just seems to drag the motor down but overall a fairly competant 4wd.
Your suggestion of slipping a newer 7.3 powerstroke makes sense,or maybe getting a big garret turbo fitted onto existing eng but even doing that could open up a can of worms apparently.
Ive just been toying with the idea as have a trip planned up through the central part of the state which is notorius for being harsh and the fact il be towing an off road camper trailer.
There are car wrecking companies here in Oz with contacts in the states just bringing in sea containers full of ex-roll over engines ie dare i say Duramax,pwr strokes etc and these guys are cleaning up.
One of these guys even suggested the newer 6lt ford oil burner whats your view on these.

 

If you turbo your engine and get it dialed in it will match the older power strokes as far as performance, without the electronics to deal with.

 

thanks for that

 

So I'm guessing that you have your ride setup for some serious overland. We love pics on this site so post a couple photos and let us see what you're working with.

Like bashby said. Turboing your motor would be the easiest way to go. Yeah, it maybe a pain in the butt to get it dial in but once you get it there you'll be golden. You could also look into things like propane injection for a nice boost of power. If you have them available swapping to a newer 7.3 PS would be ideal but whatever you do, don't, don't, don't think about using the 6.0 turd. Especially if your life is going to depend on the reliability of your truck. You will probably die!

Roll on down to the diesel forums on this site. There are a bunch of die hard oil burner fans down there and I'm sure they can help you get the most out of your current engine. They can also tell you why the 6.0 sucks. Just be careful that you take everything they say with a grain of salt. The diesel bandwagon can be pretty rabid at times defending what they think is an ideal combination.

 

Yeah,i noticed a lotta passion is displayed here,i just admire the options you guys have in the states.
not saying we are lagging behind but the jap ****ters are so much more popular here,i guess due to availability and so after market accessories /parts are aimed at them.
will get some pics organized for the gallery soon,again thanx for the feed back/advice

 

I am one of the rabid diesel nuts...

Swapping any powerstroke (7.3 or 6.0) is not straightforward. Both engines are computer controlled. So if you want one of those, you'll practically need a running donor truck for all the wiring. There some members in the 94 to 97 PSD forum that have swapped the 460 gas to 7.3. I think there's one guy who went 7.3 IDI to 7.3 PSD too.

Really, if want diesel and you want power, you're best off with a 12V Cummins. There are literally dozens of companies (at least in the States) who offer products (even some kits) for installing Cummins 12V in Ford/GM pickups. The 12V use mechanical injection (no fancy computers) and can make ridiculous amounts of power and torque.

Look into the 5.9 liter ISB Cummins (that's the 12V) before 1998 (I think). You can use the 24V with the correct stand-alone computer controller. But that's $$$$

Good luck!

 

I was always under the impression that Fords were a big deal down under. Hell, Mad Max even drove one. Some of us Yanks have always been jealous of the Falcons and Utes y'all got to drive. The long run of Cleveland engines and the evolution of Ford's I6s down there were something we always lusted after here in the states. We always figured that life was good for a blue oval fan. But I guess that we don't know if we're not there. The last time I went on Ford Australia website it looked like some of the cool cars had traded in their big V8s for diesel I6s.

 

Yeah sure Fords are a big deal here,the utes are awesome and
now with the option of the 450hp/ 330kw supercharged stock v8,and rivalary is fierce with the competition,(google aussie v8 super cars series) you may have even heard of it. This series so i have just heard on the grape vine is opening its doors to international drivers so that will up the spectator and media coverage,i do believe they might even be planning a promotional trip state side.
But as far as 4wd yeah im sorry to say the toymotors,nissans are the field leaders.
They have only just stopped importing the Brazilian made F250 due partly i hear to bad emissions but out of that descision came some good cos now theyre importing the f350/450's direct from the states which in my view is a win win situation.
what peeves me is your looking at well over $100,000 fully converted to right hand drive and our dollar is comperable with yours remember
Which brings me back to my ole girl she is yank iron,being a private import.
But your right V8's will never go outta fashion here.
