Here's a bit of a lengthy update for you guys.
So first off, I ordered what is called a "Marti" report. What this is, is official documentation licensed for use by Marti Auto Works by Ford Motor Company. This report, gives me all kinds of neat information, like when the original invoice was filed, when the truck was bucked, actually built, the dealership that sold it, options it had etc. Basically what it boils down to is that this truck was a F150 "Custom Explorer" with no options but a 302 engine and power steering. It didn't even have a radio! Along the way, things like power brakes and the 351 engine, transmission etc were changed, the truck has been painted and lost it's stripes and its manual transmission etc. The other cool thing is that they offer you the option to have a copy of your original invoice, dealer lot window sticker, door sticker and door warranty data plate if you so choose to order them. Here's the copy of my report:
As you can see, many things have changed over the course of 41 years, but these are verified records from Ford themselves that verify how this particular truck was ordered when new. Interestingly, it was ordered as dealer stock to have sitting on the lot.
Here is a quick (read: AWFUL) photoshop I made of it to basically kind of show how this truck looked when it was new. The biggest discrepancy is whether or not the "Explorer" emblem was above or below the marker light; I have seen both. I didn't edit the tires to blackwalls.

I went to the junk yard a couple weeks ago and scored a turn signal lense, so I cleaned it and installed it along with one of my original lenses, and removed the cheapo Mexican made lenses that didn't fit worth a crap. They were installed when I banged it up in 2018. The factory lenses are a little faded, but look good otherwise.
Then, this past week/few days, I jacked up the truck and began to remove the transmission, as it was super covered in grease and grime and I wanted to degrease and repaint it. Someone had painted it blue when it was rebuilt. In the process of removing it I discovered that 2 of the 6 bellhousing bolts had mysteriously disappeared. If that wasn't enough, the front frame crossmember that bolts to the radius arm brackets was missing bolts. Once I removed those the transmission came down and out with ease, giving me a LOT of room to really get in there and clean the frame up, which will be happening soon. Everything was covered in grease, almost 1/8th thick in some spots. On the flip side, I did see that whoever replaced the brake lines used copper nickel line, and the oil pan had all stainless bolts on it, and the freeze plugs on the block got replaced with brass ones. All hardware I removed will be replaced with stainless counterparts.
I packed it up and called it a day once I got the transmission out and home.
I began to start cleaning up the crossmembers and transmission by wire wheel, water and degreaser. Once I got the crossmembers cleaned, I hosed them off and dried thoroughly then primed them with self etching primer and black gloss enamel, same as used on the transmission. I sprayed the converter with Ford blue enamel. I also hosed down the transmission with my pressure washer to get the hard areas cleaned. I left the bottom of the bellhousing alone and unpainted because it was pointless to do with me pulling the pan off and flipping the trans over.
Once I got it back in the garage I drained the old pan (which had 20-30k on the fluid and filter since its last replacement and is about due anyway), and turns out all those bolts were loose leading to some leakage. I purchased a deep B&M pan kit from a friend cheap, and realized it was missing the gasket for the extension pickup for the filter; no biggie, the local transmission shop charged me $1 for a new gasket. So for now, she's almost reassembled and ready to go back in the truck. Next step is cleaning and painting the frame under the truck, and then I can begin plumbing the transmission lines as I am converting everything to AN fittings and installing a B&M super cooler and Derale external filter system.
Another big step but not pictured here is my fuel system upgrade. I have/will be installed a Carter fuel pump and the entire fuel system is being converted to stainless hardline, stainless braided hose and AN fittings (those blue and red fittings you see on racecars
). I wanted to do this to rid of all the clamped connections as the last thing I want is a fuel leak and fire on my girl.

I also removed all my bracketry and pulleys to get them ready for sandblasting; not everything is shown here.

Now here is where the fun begins. The original plan was a basic cam swap, and as you can see, that didn't exactly happen. I purchased a 429 engine a while back with the intent of building it while the 351 was in the truck running, but after rethinking it, the 429 is almost 300lbs heavier than the existing engine and it would just drive like crap. It's already front heavy as it is, and without upgrading the front coil springs it would just be awful. That being said, as you can see above, I teased Boss 429 valve covers and the original idea for this truck was to convert this Lincoln car 4 barrel 429 over to a Boss engine, but I have decided against it. Space (lmao its a truck) is a big factor believe it or not with the Hemi heads. I did a lot of research and spent a lot of time measuring, and ultimately with the steering and brake stuff being in the way it wasn't worth relocating.
Last week, I removed a 400 engine from my friends 78 F250 Camper Special. There was nothing wrong with the engine and ran beautifully, other than it was doggy and threw a tantrum pulling his race car trailer especially backed by the 4 speed. He had a new engine built that should make about 400 horsepower. Since I am doing all the work to swap his engine, he is giving me the old 400, for free. This engine has about 15-20k miles on it since rebuild and the short block is in excellent shape. I was going to remove the adjustable valve train and put it on my cylinder heads I rebuilt in the above post, but then something happened.
Basically I've been talked into building an engine, and to do it now while the truck is apart. I can get the 351 running as is, but, as it so happened to be, I want some HORSEPOWER. I'm taking this 400 apart that he gave me to see what it has for pistons...if I like what I see for compression then I will use that short block; if not, I have 4 engine blocks to pick from and having a rotating assembly installed and machine work done will only cost me about $1400 which is reasonable and far less if I assemble it myself. I am looking at picking up Trick Flow 195 cylinder heads with a 72cc combustion chamber that should yeild me about 9.3:1 compression with a flat top piston at 0 deck which brings the piston up .070" in compression height. The stock compression height sucks which is one reason why stock 351M and 400 engines only made 156 and 173 horsepower respectively. These heads with a very mild cam (and I stress very mild) will pump out 400 horsepower and 500tq on pump gas (93 octane). This is a very mild combo and odds are I'm going to throw a far hotter cam in it. With not much else done to it, a few videos I have seen have had these engines north of 550hp. I don't plan on going that far.
Now that really fun part. Boost and/or nitrous. The biggest problem I'm going to have with a power adder is the stock connecting rods. They are super long and no one makes aftermarket rods. You can use Chevrolet rods and Dodge 340 pistons (or a 351 Cleveland piston), but then you run into the problem of the wrist pin being offset .026" which puts a side load on the cylinder walls and causes premature ring and bore failure. However, these engines will safely run up to 150hp shots of nitrous bone stock, so with heads, compression, opened up ring gap and timing pulled I can theoretically run more and that would be fun. I have been considering boost and turbo kits, but that's so far in the future and expensive as compared to nitrous (kits start at $500), so I'm more worried about getting this thing running and having some fun with it first before I really start looking at power adders.

This week I am going to start sanding and priming/painting the inside of the frame and things I can easily get to now that the transmission is out of it. I also have a massive stock pile of new parts for this thing (roughly $3,000 worth!) that are laying around waiting to be installed like new shocks and boots, wheels etc. I am also currently into looking into installing ladder bars or putting slapper bars back in for some kind of traction device. Ladder bars may have a problem with clearance of the frame rails, so I'll keep you posted.
What started as a simple camshaft replacement, as expected, turned into a whole wild thing!
