I picked up a non-running '87 F350 several months ago - it's a crew cab 2WD truck with a 6.9 diesel and ZF5. It's been a bit of a journey trying to get the 6.9 un-stuck, souring a turbo 7.3 IDI that ended up being junk, then buying a 1988 F350 plow truck with a good motor and junking the rest.
Right now, I have a 4x4 ZF-5 in a million pieces in the garage, and next up will be the transfer case and the 7.3 IDI.
I started a YouTube channel recently, and pretty much everything I have done on the truck is on it - you can find it here - https://www.youtube.com/c/THEBULLETPROOFGARAGE/videos
Also, I'm still somewhat new at YouTube, so if anyone has any input or recommendations, please let me know.
Thanks!

Cool project. I subscribed to your channel.
I have an '85 Bullnose Dually that shat the 6.9 in the spring of '21. I ended up putting a 7.3 shortblock under the 6.9 heads and installed the 7.3 Turbo and intake. I am also running the original T19 4 speed with an Advance Adaptors Ranger Gear splitter OD. Much different truck with the IDIT in it. Let me know if you have any questions, although I won't be much help with the 4x4 conversion.

Wow! That is one beautiful bullnose!
On the 6.9 heads on the 7.3 short block, did you just drill out the 6.9 heads for the larger head bolts? Is it a 7.3 turbo short block with the beefier rods or is it a NA 7.3 short block? I have two sets of 7.3 rotating assemblies, one turbo and one non-turbo; need to figure out what to use.
What turbo? OEM setup? I have an OEM setup but not sure if I'm going to upgrade.
What IP and injectors did you go with?
Thanks!

The 6.9 heads are actually drilled to just under 0.500", which means they will pass a 1/2" threaded rod, but not a 1/2" bolt shank. Also, by time you have all 17 bolts and position tolerances to worry about, something isn't going to line up. So I just reamed the holes to 17/32", and everything worked fine.
I am using Classic Diesel Designs turbo kit. Which is essentially a stock 93/94 turbo setup with a few ATS pieces thrown in. I am still running the 6.9 pump (or whatever pump the Ford dealership in Lafayette, IN put on it when the original went down as I was passing through town 6 years ago.) Injectors are from Accurate Diesel, but I have a 2nd set from CDD on the shelf incase I throw a bigger pump at it.
The pump is definitely the limiting factor right now. I don't have it turned all the way up, but it is close. Very little black smoke at load, and EGT's rarely exceed 1000 F, the temp probe is in the passenger exhaust manifold. Peak boost is about 10 psi with the waste gate blocked off. I also had Oregon Cam grinders regrind the cam.
I would suggest running the turbo rotating assembly regardless. The heavier wrist pins and rods are just good insurance.

Thanks for the details.
I hear you on the turbo bottom end; if I can get pistons, I'll end up using the turbo rods.

Nice truck

Thanks, @Gkskull.
Been making pretty steady progress. The ZF5 is in a million pieces while I try to source an un-cracked 4x4 extension/tail housing for it. In the meantime, I have started working on the 7.3 IDI turbo build.

Hurry and get it on road! Will you use it to move back to TX?

Hey Randy - It's getting close! Engine and trans are in and I start the transfer case (BW 1356) rebuild this weekend.
Will probably sell the truck in June or July, but should be running and driving by then. Too many projects stacked up back home in Texas.
