How difficult would it be to swap my 6.9 and possibly my 4 speed into an OBS Ford? Obviously starting off with one that was a diesel is going to be easier but what all would it take for both a gasser and diesel truck? Has anyone here done this swap? Its just that I don't care for the 80s body style and plus most of the stuff I need to fix on my truck isn't motor or tranny related. I was thinking that if I could pick up a 92-97 F-250 or F-350(prefer the 350 just for the D60 front) with a blown motor and just swap in my 6.9 then I would have the body style truck I want, I wouldn't have to worry about cavitation like on the 7.3 idi, and if I can score the right truck I can get an OD tranny.

 

I'm doing a 86 into a 90 and converting it into 4x4 alo, everything is fairly simple. It all bolts in notin to wrry about. I had a hard time finding a flex plate cause I'm using a e40d on my 6.9 and I didn't want to spend bout 200 bucks for a new flex plate. And also since my 90 is 2x4 I have to drill holes in my frame for the front spring hangers. If you get a gas then you have to use there sending units off the gas motor and some off the diesel. And it was only the early 7.3's that had cavitation problems from factory the sleeves were .45 thinner in number 7 cyl. than the rest of the sleeves

 

I would imagine that if I find one that had the 7.3 and ZF5 in it that my 6.9 would just drop and bolt in with the proper clutch.

For a gasser, 460/ZF5, I think for the most part all I'd have to do is get 7.3 idi motor mounts, drill the correct bolt holes on the bellhousing, get the correct clutch, swap in a diesel gauge cluster and the tanks off my truck. Would there be anything else?

To be honest, I'd rather go back to an auto but the ZF5 looks to be the easiest and cheapest option, other than swapping in my T-19. Will a ZF5 for a small block hold up or would I have to get one from a 460? Its just that there's quite a few F-250s around here that have 351s and since its farm country, they're pretty much all manuals.

 

You wouldn't have to drill the bell housing cause ford and international have a adapter plate the converts the IH motor to fords tranings. I don't think a zf5 from a small block will work but don't hold me to it bud. Other than that get some motor mounts and the cluster from the diesel and some other parts and you should be set. And personnaly I wouldn't swap gas tanks. I am keeping my tanks from my EFI so I never have to worry about priming it. I got rid of my lift pump and went to kragen and got a adjustable fuel pressure guage so I can crank up my rail pressure to my I.P when I want to, The most it will go to is 5.5 psi so thats good enough for me. just my .2 though

 

What other parts are you thinking? As for the tanks, on every gas to diesel swap I've read about, they swapped the tank for a diesel one for some reason or another. I've heard that some gasser tanks are lined with zinc and that it wasn't real great when the diesel met up with it, so to speak. And when it comes to fuel systems, I really don't know anything so any help explaining there would help.

I found this 97 F350 crew cab long box, which is my dream truck, with a blown 460 and no tranny(don't know if its an auto or manual though) but the guy must be on crack because he wants 1500 bucks for it. It looks like its in good shape but for something that doesn't run and can't drive, I can't imagine paying more than $500.

 

Some other parts as in lines and some bolts and wires misc. stuff. And I'm pretty sure that doesn't matter for the fuel, if it does oh well, I'm pretty dam sure they all use the same tanks they just put electric pumps in them for the EFI systems. That aint a bad truck is it 4x4? And I would offer the guy like 400 bucks at best. And your dream truck is probilly my dads , take a look at my pics and u'll see it

 

Yeah something like that. That body style CCLB 4x4, with one of these three power plants: 12v CTD, IH DT360 or DT466, but as long as she's got a diesel under the hood I'd be happy.

That one is 4x4. I refuse to buy a 2wd truck. And that big front bumper comes with it but I'd probably end up swapping the one I built onto it instead.

So I understand right. If I just used the gasser tanks with the factory pumps, it would be like adding an aftermarket electric pump into my current system? Should I just run the factory tanks, but switch out the lines to diesel lines or would the gasser lines do it? I'm not sure if they are different or not.

 

12v swaps would be a lil harder. And 4x4's are deffintly worth it if you have the use for them.

As for the fuel lines I would keep them and yes you will have a inline fuel pump just go and by a adjustable fuel pressure guage at kragens cost me 30 bucks and goes from .5-5.5 psi. I just made a plate and covered the hole for my lift pump.

 

Ok. What exactly does it do and where should I set it?

 

it throws more fuel to your IP and under your hood some where
