Hahaha, got a good chuckle on that, Ross...

Got it figured out (sort of). The pump adjustment was off, closer to 9/16" stroke; brought it down to 7/16". This almost immediately solved the issue of the stall at WOT, but still noticed it just being a little, I'm not sure... lazy I guess, so now I go back to timing (because what else could it be). I stuck the light on it and it showed the 10 degrees I would've expected. But just for fun, I brought the timing up until it the engine started to stumble, and backed it off. I tried to put my timing light on it, but even messing with the advance adjustment on the light, I couldn't determine to what extent it was now advanced, but certainly flashing inches away from the marks on the balancer. Either way, it seemed responded well to this adjustment without discernible "pinging." So I can only assume that the timing was retarded.

So while I got the result I was looking for, I'm also confused. The harmonic balancer was rebuilt maybe six months ago, and it has NOS timing gears and chain. I'm relatively certain the marks on the gears were aligned when I installed them, and they went back on their respective keyed shafts without much fuss. Possible that the balancer was rebuilt incorrectly, or are there other reasons the engine would seem to want so much advance? Thanks, guys!
