This would be a good time to explain the "long story".

This particular 1973 is actually the third and fourth pickup I bought before 1998 (when I was on leave during my time with the Army). My first pickup was a 1974 F100 4x4 shortbox that I purchased in December of 1992. The previous owner called it the "Johnny Cash pickup" because it was exactly that...a lot of spare parts thrown together to make one. It was a basket case but it was $400 and I was a broke freshman in high school. The following year I came across a 1976 F250 2wd with a blown-up engine. The body was immaculate so I bought it for $400 and swapped the cab. Since the F250 was obviously a long box and wouldn't work on my shortbox frame, I built a flatbed for it. This was my first taste of how useless a shortbox pickup was for ANYTHING (especially being a flatbed) so........

The real pain in the butt was realized when it came to title work. Six months of inspections and a grand total of $500 later, I had a bonafide title for a 1976 F250 that started life as a 1974 F100 (and I personally called an F200 because it was a coil-sprung, eight lug pickup by the time I was done). I told myself that I wasn't going to through that bullschtein again. Yep, that's ORIGINAL PAINT.



So...

I bought this 1973 F100 2wd pickup in early 1994 from a local rancher for $200. It had a 302 (with two burned exhaust valves), 4 speed, and a full-time ventilation system through the floorboards. It was beat to hell, but it was my first "toy". The first order of business was putting in a 390, C6 and painting it. I did some body work and made it the "Silver Bullet" (it originally was the same blue as the first one).


Later on (on leave in 1998), I found ANOTHER 1976 F250 2wd (AGAIN, the same blue as the first two although the paint wasn't very good) with an immaculate body and a blown engine. Here's where that got me. Oh, by that time, I had replaced the 352 in the 4x4 with the 390 that was in the 2wd and put a 460/C6 in the 2wd with the "lots-o-nitrous" mod. You can see the previously-pictured 4x4 way off in the background. I hadn't yet built the airbag/3-link rear suspension either.



Since I wasn't going to go through the rigamarole of the whole inspection/title process, I removed the VIN stuff from the original 1973 and put it on this cab. Illegal? Yes. Do I care? No.

So I drove the 1973 2wd from 1994 to 2008 through two cabs, three boxes (used the box from the first 4x4 build hence the no "dent trim" on the box but the holes that I have to fill on the cab and front fenders) and three engines. Now, it's on its third iteration...a 2002 Powerstroke chassis.

I had to cut the front under-engine crossmember quite heavily for oil pan, oil filter, and starter clearance. If you take a look back at the frame comparison picture, you'll see three sets of identical transmission crossmember mounting holes. All I had to do was use a different set of holes....no drilling required!

On edit:
The most expensive part of this thing so far (minus the initial investment of the wrecked 2002) has been new driveshafts. I had to get a much shorter front (and got rid of the worn-out double cardan joint) and a longer rear driveshaft (again, with the POS double cardan delete). Those Spicer flanged yokes are 'spensive!

Just some more random stuff that I took before finishing things up under the hood. The underhood wiring has been done and the present project is intercooling. I have the custom intercooler mounted (Tugly mentioned a shoehorn) and believe it when I tell you that I don't have to modify the stock SuperDuty intercooler pipes AT ALL to make either one work.....

Hydroboost:



2002 lower core support attached to the 1973 core support and coolers installed:



Stock fan and shroud:

The ONLY reason I kept the ABS module was to supply a VSS signal to three other modules.....Stupid engineers.

Hybrid steering shaft:
I installed a roller bearing in the bottom of the old column, grafted the end of the 2002 shaft to the old shaft, and shortened the original column-to-sector shaft.

I did a bit of research this afternoon on the Super Camper Special trucks that have the extended wheelbase.

To properly fit one of those bodies, the frame would have to be extended (or start with a Supercab version of SuperDuty).

Well, if I do this, it'll be with either a king cab, or a crew cab, and a long bed.

I've put a touch over 600 miles on it so far.

Runs, drives, handles, and sounds like a 2002 Powerstroke.

I pulled a trailer carrying a Ford Escape the other day. All trailer wiring is fused and uses relays.

I bought paint on Tuesday. Ford code G9 "Vista Blue Metallic".

Fuel gauge, temp gauge, oil pressure gauge, speedometer, aftermarket tachometer all work. Cruise control and ESOF are flawless.

Not much else to say at this point. I'm going to try to get the step bars off of the 02 cab to mount to this one. I'm too old to be jumping into stuff anymore and I hate it when people use the doors or steering wheel to pull themselves in.

I see Tugly alluded to some a little bit of technological work, but how did you get all the gauges to work with the sensors?

Navistar decided to use standard pipe threads in the water pump housing and oil cooler housing. I just screwed factory 70's era sending units into the holes and extended the stock cab wiring.

I think Rich was talking more about the ability to make the mechanical speedometer work with nothing more than a signal from the ABS module.

Oh, ok, makes sense on those, I take it the same with the fuel gauge then?

How did you make the speedometer work? A group here at school built a working speedometer with a speed sensor, an arduino, and a stepper motor hooked to the needle on the gauge. Is it a similar setup to this?

I enjoy these older trucks and these DIY electronics projects, so I am curious. Hope I'm not bothering you with all these little questions.
