My New 1970 F-250 4x4 Fire Truck
The truck is a 1970 F250 4x4 with a 360 and 4 speed manual just over 17k miles on it. It was originally used by a local fire department near my home town. My friend's father bought the truck from the fire dept in the mid '90s and used it for heavy loads and trips to the dump. Recently, my buddy and I spent few days working on the truck, getting a start on some needed maintenance. It had been parked for around two years but started right up with a battery and some new fuel line. After a quick wash with an electric power washer, we drove it inside and got to work. We had to find a couple 8-lug ford steel wheels. The truck had two newer E250 wheels on the front but the rear still had 16" split rims. A local junkyard had some rims available and I was given a reasonable set of 16 inch LT tires from some 2000's suburban rims sized 265/70/16.
A few major items were immediately apparent. The brake pedal went to the floor with absolutely no pressure, the engine had no coolant, and everything was quite oily. We bled all four drum brakes and got really strong pedal back, at least for now. It needs a major brake overall; definitely all new brake lines, wheel cylinders, and hardware. I also think the master cylinder was leaking while we were bleeding the brakes. I plan to reuse the the drums and shoes if they are in good shape - any opinions on that? Pretty sure they are original.
The thermostat housing was clearly leaking through the upper radiator hose clamp. I cleaned it up with a wire brush and installed a new hose/clamp (and thermostat). It looks like it could easily lead to another leak - should I replace an item like this? We also removed the fan/shroud/radiator with the intention of getting the radiator checked at a local shop. At the guys recommendation, we replaced the original radiator with one from O'Reilly's. While the radiator mounted up with no issue (for bolts or hoses), the fan shroud doesn't seem to fit - has anyone else experienced this issue?
As for specs, I haven't figured out all of the details but the truck seems to have a Dana 44 with closed knuckles up front and a Dana 60 in the rear. The 360 runs smoothly, although it does have a cracked exhaust header which will require replacement. I've read that the stock setup is quite restrictive and that a set of headers is a great addition to these motors, anyways. Other than that, I've already replaced most of the rubber on the engine and I'm looking to change all of the fluids. Do I need to use the ZDDP additive in my oil? Also, Is there a specific type of 50 weight oil I should be using?
Overall, I'm very excited about this truck. First thing, I want to get the truck safely running and driving before I look to do any upgrades. There is a little bit of rust under the battery box but otherwise, the truck is completely clean. The huge bumpers are extremely nice for working in the engine bay and for reaching into the bed and they will definitely be staying. While I want to add headers soon, I'm probably going to run the stock intake and carb for a little while.

Congrats. Looks like a fun truck!
Oil... go with Shell Rotella T 15w-40 meant for diesels. No synthetics.
Gear oil? I use Lucas 75-140 although 80w-90 or 75w-90 is also acceptable.
Btw, ditch the points and get a Pertronix module. Smooths out the idl, is trouble free, and dead nuts reliable.

I'll take a look at the diesel oils. The truck came with a case of 10w-40 Havoline and a couple of Motorcraft filters, so I wouldn't mind using that since it won't work in any of my other vehicles. It also came with a case of HD50, presumably for the trans/axles but I will probably look at using the lucas gear oil instead.
The Pertronix is high on my list. I watched a couple of Youtube videos and it looks pretty simple to install. Can I leave the stock coil or do I need to upgrade to a Pertronix (or other) unit?

The 50wt. is called for in the tranny & transfer case for easier shifting. 30wt in cold weather country. Check for a glove box hand book with all the info & spaces oil types
90wt in the axle ball end u-joints engage hubs every 1000 miles to lube upper king pins axle u-joints.
Nice find have fun with it!

Man, you jumped in to the World Of Bumpsides with both feet! Way COOL find! Long bed Flareside and all. If you ever get it "restored" nice and pretty you ought to ask the Fire Chief if you can put the letters back on it. I'd take measurements and pics of those door letters now. Just in case.
