Welcome
Thomasbuilt!
Nice piece of family history you have there.
Which V6 engine and carb do you have? Either way I'd put a fuel pressure gauge on it to see what's happening there. Photos of what's cooking under the hood may help. Ignition coils can heat up and funny as well.
What kind of symptoms are you experiencing?
I had issues with mechanical fuel pumps; maybe because they were old stock and had sat on the shelf too long. I went electric FP.
