Everything seemed to have played in my favor yesterday. The truck idles good, I swapped to the lightest set of springs for a bbc in the distributor, moved the vacuum hose to the other side of the distributor, reset my timing around 9 degrees, put in a mechanical water temp gauge to rule out an "over heating issue" and let it idle for 20 minutes. All was well until I tried to drive it. It has good power now like it did before the fire but it dies when I let off the gas after driving. I think the only thing it could be is my idle mix screws are off (correct me if I'm wrong). It fires right back up with a quick bump of the gas pedal. I'll be adjusting those when I get home today.
