A few months back I stumbled across this F250, I like that it's a "real" truck, longbed, 4x4, diesel.

It was pretty cheap, only has 185,000 miles on it, starts easily, runs well other than an exhaust leak..

Downside is it only has reverse, and it's rusty AF.

Like, punt the entire body kind of rusty.

Guy who owned it, pretty sure he kept every piece of trash he every brought into the truck since 1997, in the truck.

So I haven't really decided if I want to throw a few thousand at it and have a decent, simple work/camping truck... Or just pull the engine and collect my money and be done with it.

Cabs are easy enough to find and cheap enough to buy, I just don't know that I feel like doing another "build" with my 4runner, C10, D100, and entire shop and powder coating also going on.

But if I do decide to build it, I'll share it here.

I thought I'd just grab coils from Marketplace from someone who did a lift, but no one seems to be selling them.

That's ok though, because today when looking for a new head for my Toyota, I found this 11 Super Duty that will donate it's coils, shocks, rear leafs, track bar, and track bar bracket. View attachment 282844
This is a win for sure

I just saw a guy on Youtube who used Super Duty axles, a 2" spacer and wound up with a 5" block in the rear. So my guess of at least 4" was close.

I'm going to be using longer 08-up Super Duty rear springs, because they should ride nicer. Planning on doing a shackle flip at the same time, and that's where I'll make up most of the height difference to the rear.

I bought these for the wheels, I'll powder coat them in the summer when it's all back together, but the 285's look clown shoes even without fenders lol.

I have the axle set at what Ford lists the spring installed height at, 14.7", so it will likely chnge one way or the other in reality when I get springs on it and the weight of the 7.3

Ran out during lunch yesterday and cut the shocks and sway bar links off my junkyard donor to snag a set of coils. Local walk in and they hand you a part style yard wanted 100 per coil, Rockauto has them at like 180 a piece... Plus isolators.... Self serve, 10 bucks a piece lol. I'm willing to push the stupid gantry 1/4 mile in the 30 mph wind gusts to save 200 bucks.

Still need to rob that thing of the track bar and drag link. I'm not certain the track bar will work, but probably better to have and not need...

I'll try to get these powdercoated Sunday.

I've been on and off the fence about injectors.

Me paying 1400-2000 for injectors for a work truck is simply out of the question altogether.

But I've done a bunch of digging and reading, through some very old posts, and this is what I've come up with, and I suspect some of the current injector builders read some of the same old Powerstroke Army posts lol.

Anywho, before I was an engineer, I was a journeyman machinist for years. And it just so happens, I still have access to a bunch of surface grinders. Why does that matter?

An AA code 7.3 (stock OBS) injector flows 90cc and uses a 6.0mm plunger, prime barrel, and a 32mm long intensifier piston...

An AC code is identical except the intensifier piston is 29.7mm long and flows 160cc

From this, we can infer that 2.5mm in intensifier piston height = 70cc of flow...

From that we learn that .0357mm off the intensifier piston will give 1cc of flow.

Every 10cc needs .357mm taken off the intensifier piston...

So a 90cc AA code 32mm piston needs to go down to 29mm to make a 180cc single shot 7.3 injector. Or 29.7 for a 160cc injector.

Further, oversized nozzles come from Redat, PN ARF0AA, there's a -, followed by a number, so like, ARF0AA-100 would be a set of 100% nozzles, ARF0AA-80 would be 80's, etc etc. These are available in the states pretty affordably from Bitteroot Diesel.

I said all that, to say my intention is to build a set of 180/30 injectors over the holidays 😁 And leave the information for anyone else interested in the future.

Man this thing is coming along!
Lucky there's no snow yet. I hope it holds out for you
Snow or not, I'm done with the outside portion for the year, I can't handle hours and hours in the cold like I used to.

I'll be doing the injectors, oil pan, and transmission rebuild inside the shop over the winter, along with my other project stuff.

I also need to build a real powder coating booth to spray in, and make some improvements to my oven.

Planning on a trip to Florida in 3 weeks to visit family and either pick up a parts truck or parts.

I'd like to put the 80-86 style front clip on it, but hardly the most important thing in the world to me at this point. It seems Florida is filled to the brim with these trucks though lol, there's dozens in the junkyards and on Marketplace for under 1k.

Where abouts you going to in Florida?

Pulled the injectors last night from the drivers side.

One had RTV on it for some reason lol.

One is also clearly a replacement, the top piece is a drastically different color than the rest. It also has some writing on it I can't make out. The part number is different as well. Still an AA code prefix though.

I plan to measure the intensifier pistons against one another, and the new ones against one another, just to see how close they are stock.

I purchased 29.7mm intensifier pistons from Interstate McBee to make a 160/0 single shot. They were 20 bucks a piece, with shipping came to like 198.00

The manifold is drilled and tapped.

I'm not replacing any cups.

I'm only taking these 4 apart to compare the stock intensifier pistons to the AC code replacements, and to compare all them to the passengers side ones I cut down awhile back, because it amuses me to see "injector builders" who were ten years ago posting in DIY injector threads, now telling people they can't possibly make their own injector.

The passengers side are already cut and re-installed. Once I finally found the parts and saw they're only 20 bucks to buy, I wish I'd done that to start with.

Most of you probably don't know, but the 94.5-97 Powerstroke trucks got a different, deeper core support than any IDI or gasser.

A lot of parts houses will list the others as compatible, but they're not the same, my radiator is like 8" taller than the others.

So LMC carries them for 350, plus 220 shipping...So I've been hunting for someone who changed directions on their build, abandoned it, etc etc, and I found Jeff's Bronco Graveyard carries them, and I can pick it up in Brighton, which is about 90 minutes for me, to save 220 bucks.

Further, they had a damaged one for half off! 175 bucks, and I was seriously considering patching my original one together with the plasma table lol.

Merry Christmas to me! Hahaha

Injector builders are the Ford-Trucks forum are super mad I'm building my own injectors, it'll never work, blah blah blah. Hilarious.

Went down and picked up my core support yesterday, it's actually the correct one, I was concerned it might wind up being a gas version after a 90 minute ride, will try to get this powder coated this weekend.
