Well, blown the 3rd heater core this year, I'm going to check all the grounds, and the coolant checked negative for electrolysis, gonna tee in a pressure gauge to check the Pressure​ In the system.
Since I have 2.5 weeks until the truck needs to be at JRC mud bog(1.5 until I want to take it out for some test passes) I guess I'm gonna do some tinkering tonight. My parts stack consists of front shocks, mufflers, tach, oil pressure gauge, coolant temp sensor, Transmission coolant lines and electric fan.
Probably gonna start with the trans lines, and maybe mounting/wiring the fan (If I can find the mounting tabs I have for the fan). Then to wire in the gauges. Plan is to get it ready to fire and hopefully make it run, then work on stuff like exhuast, shocks, and hooking up brake lines.
Josh, is that measurement to center or outside of the frame rail?
I will measure it next time I can get out to the garage.

Outside to outside. However the collective wisdom believes it should fit.

so I'm not sold on the electrolysis theory yet. So random voltage (ac or dc) energizes the coolant and then finds the weak point of the heater core? And where does it jump from there? To a bolt in the heater core case?

What coolant do you use, Dustin?
Was the first one that leaked the original from the factory?

There's a ford tsb on it, it corrodes the heater core from inside out. I doubt it's that. It pretty much puts a current through the coolant and the heater core is the weaker material vs cast iron and brass. Shows 0.095-0.1 volts, vs Fords test minimum is 0.4 volts.

So you can probably rule that out, for now. I wouldn't want a ground on the heater core unless it absolutely necessary, then you are just giving the voltage an easy run, which may raise the level.
So the other options are junky made parts or pressure too high. How are you filling the system. By pouring it in then burping it? Or vacuum fill?

I'm not adding the ground, ordered a Ford core, it's bent, returning it and getting another one.
I'm filling it and running it, no burping or vacuum filling?
Gonna try to tee in a pressure gauge this weekend to check it, that should check the cap.

Good deal. If you want to vacuum fill it let me know and you can borrow the unit I have. It pulls a vacuum on the entire system. It allows you to check for any minor leaks. Then when you release the vacuum you have it pull in coolant, the entire system gets filled, no burping no air pockets. Works really well.
Finally got the oil pressure gauge, temp gauge, and tach hooked up. I also got the electric fan hooked up, then connected everything to the battery and tested everything individually. Then put a little gas in it and tested the fuel system, gas 2 small leaks I had to take care of. Then popped the distributor out and primed the oil pump. Not to bad for a 21 year old engine I guess.
Just when I got ready to try to fire it, it started storming.
Got it to run, sounded decent for not running in 7 years.
unfortunately the powersteering pump locked up and shredded the brandnew belt.
So list consists of....
Throttle return spring
More coolant
brake line
another new belt
new power steering pump
new powersteering pump high pressure line
Slapping on the mufflers
bolt up the shocks
Then maybe I can test drive it.
