Prepping 534 for long trip

Hi folks -
Newbie here, but grew up with C series trucks in the fire department and just bought one. 1970 C850. 5sp. Very nice shape. Fire body removed. But here's the question:

I need get it from FL to CT. It has 17K miles on it. I think I might drive it, burning the numbers off my credit card for fuel. What should I do to prep it? I don't know exactly where it's been recently and what condition internals are. It looks good and sounds good. I'm thinking things like:

- change all fluids and filters
- proactively change all belts, hoses
- maybe even change out the alternator if I can't tell age
- does this engine have flat tappets? should I make sure I have oil compatible with older engines (zinc/phosphates)
- transmission fluids, filters

And any chance I'd get over 5 MPGs given that it is empty?

Thx for your thoughts....

Welcome to FTE.

This engine has flat tappets with hydraulic lifters.

Something like Shell Rotella 15w-40 would work methinks.

That zinc thing is mostly for break in afaik, but it isn't a bad idea to watch that with an older engine.

As far as your prep, sounds good. Not sure I'd change the alternator.

5 mpg is what I'd expect.

If it's been sitting a lot you might want to change the thermostat too. Worst case, you can always remove it on the side of the road. If the alternator is charging, it should be fine for the trip.

update

thanks for the feedback so far. I've held off pulling the trigger. Geez, its a nice truck, and really cheap, but want to make sure I respect what I am getting into.

I've searched the site for parts sources for the 534 cu inch and am not finding much. I also talked to my local NAPA guy and we had trouble finding filters and other parts for it. BUT, I know there are a lot of fire departments out there still running these, so they are getting parts from somewhere. I guess I need to call FordMoCo and check.

Anyone have a reliable parts source? Hard to commit to a long term relationship with a big engine if I can't take care of her

Plugs, points, condensor. Each year, Period. Always meant about 1mpg on our '73 L900. That would take it from 3mpg up to 4 mpg, even if it sounded like it ran fine.
