Dropped idle timing a lot and richened it up...idles much better, but far from perfect.
74 vs 72. I think it was same stretch of road.
Feels just like it looks. Good pull down low and drop off up top.
That was fun for a minute...Pulled back into drive after cruising a few miles and coolant overflow was
overflowing and boiling. Temp was normal the whole time.
Oil is clean. Oil pressure good. Runs GREAT, except for what feels like spark blow out and overzealous coolant

. Opened up the plug gap to .025 from .018 on 3.0 (No DLI anymore, since it fried), but maybe went too far...or?
May gap down plugs and try another run tonight to see what happens. In case it ends up being headgasket, I have a set of graphite/composites from gasket kit and my A1 head studs. It's free to try if I have time this weekend between Turkey, homebrew and homemade wine
If it is a headgasket; of all the things that could go wrong on 500 lbft on a bone stock 74, I'll take a headgasket
