Didn't see any mention of a new water pump. Possible the impeller suffered some corrosion during the 15yr sit.
What does the flow through the radiator look like with the cap off?
If the heater return is to the radiator, how is it flowing?
Was the air out of the heater hot with the fan on high?
BTW - for a mix-master truck, it looks pretty nice.

When I pulled over you could hear it boiling in the top hose, its pretty hot. I have verified the temp with laser.
The air out of the heater was very hot, with fan on high.
With the cap off, engine warm, you can see nice flow through the rad. That's why I was hesitant from the start to replace it. But I am down to just a couple more possibilities here.
I will check the heater return to the radiator. All hoses are very hot, though, so I believe that the flow is there.
And thanks, its a bit of a head turner, I have a few other project trucks but it is my hope that this one be my daily driver, so I am anxious to maximize my summer driving time with it.
