Mission Creep on a D-150

I got back from my buddy's place who has the engine run stand. While the cam is already broken in, I wanted to get everything else dialed in. It's getting the Offy intake and Holley 390 this go-round so it's dialed in and runs well. Now that it's back home the engine is starting to look like an engine again, hopefully this one lasts longer than the last one, eh?

All I need to do is mate up the trans and it's ready to drop back in the truck. I should be doing that today, say a little prayer for this mechanical goon that things work out.
Your friend with the engine run stand does he have an AF gauge?... I remember you saying something about getting one...
