Did some measuring, got a 36-1 trigger wheel for the crank trigger. Turned out, I screwed up my measuring. Outside diameter of the teeth is ... pretty much spot on for the outside diameter of the pulley.
Thought I'd give it a try, since there's that nice heavy bevel on the edge of the pulley/damper. If it works, it makes it a little more protected, I think?
And with that, time to fasten it on there proper, like. It remains to be seen what the runout is like, since I had no fancy tools to do this with. Will just have to try it and see; maybe fettle the heights of the teeth by hand, if it turns out to be too bad.
And then a splash of paint...
I also went through & double-checked the torque on all the main caps and rod bolts; threw some new hardened washers under the head nuts -- because apparently I lost a couple of them in the move from the previous unit. Fantastic -- and got the head torqued down, with its new O-rings and a new head-gasket.
Getting closer and closer, now, to having an assembled long-block! Head-scratching still on-going over the inlet manifold design; though I'm reasonably convinced it's not going to be a log-style manifold. I managed to dig out the original one -- which required some surgery to the truck body to allow me to extract the locker door hinge, to remove the door, to give me enough room to extract the manifold from the locker! -- to squint at.
Then, more painting...
Now the engine side of stuff is back to waiting for parts to be bought/delivered/built/etc.:
- New core plugs (On their way.)
- Got to hunt down a set of lash-caps for the exhaust valves; well, really, I only need one. (It's corrosion pitted, because apparently I didn't smother it in oil enough when I removed it along with the pushrod for the stuck valve. Ho-hum.) I'll probably ask about on hmvf once I've got the brain & cash to spare.
- Also got to get myself a cam follower, because one of those is pitted too, for some reason. No sign of any damage to the cam, and I'd rather it stay that way.
- Sump & oil-pump pickup. Indecision about whether I want to build a new sump from scratch, modify the one I have, or try and find the correct one. Building or modifying is stalled on me finally getting the money & available time to get a bottle of gas for the TIG welder, though.
- Fuel injection parts, various. (Injectors, fuel rail, fuel pump, regulator, lines, misc sensors, etc.)
- Manifolds, of course. Though I could always run it on the carb setup at least temporarily.
I should probably get back to the body-work while the engine work is stalled...
Made a minor start on body-work. Went to set the go-pro up, it
wouldn't turn on. Put it on charge, using the charger & lead that
charges my little torch just fine. Still wouldn't turn on. Then I
dropped it and got crud in the microphone port and when I went to try
clear the port, I managed to poke its ear out. All it can record for
audio now, is crackling. 
Not happy at all. Then I lost my glasses. (Absent-mindedly put them down somewhere.) Between all that, and my knee being agony, I'd had enough. Managed to find my glasses -- picture me hobbling about hunting all over the workshop, with my nose 6" off everything I'm looking at, cursing growing louder and louder -- and went home.
Hopefully it's repairable for significantly less than the price of a new one, but in the meantime -- especially since I have a budget of "No" for at least the next week, due to a combination of everything coming out at the wrong times. -- I guess I'll be making silent movies.
But at least I've made a start on reconstructing the cab floor on the passenger's side; so I'm not totally stalled for the time being.
