After re-connecting the vacuum retard (I still giggle when I say that, you don't want to know the image that pops up in my head) and adjusting the idle screw I got it to around 700rpm. I'm measuring by ear, I don't think my tach is accurate. Anyway, it sounds great. I also unplugged the ambient air sensor... At idle, with that plugged in, the car sounds like it has a miss. I thought it wouldn't have that much of an effect, but guess not. The sensor must be severely out of spec.

Car is running really awesome right now, I'm quite satisified. Next step: Completing the Crane ignition set. I've got the xr700, next is the HI6 ignition box and the coil. New plug wires as well.
