Distributor refresh gone wrong

Update: I took a few days off from the car to give myself a fresh set of eyes and hands so as not to assume or skip over something. Borrowed a compression tester so I could know for sure I was at compression tdc, was deliberate in checking all the plug wires were going to the right places and seated correctly on the plugs and distributor, verified the rotor was pointed directly at #1, and it fired up. While idling I advanced the timing to the limit of the channel the hold-down bolt is in. Engine sounded happy and the test drive yielded perfect results. The initial problem of bogging down/ hesitation upon acceleration was nonexistent. For the first time since I got the car I was able to accelerate up moderate inclines.

I had put the original points and condenser back in so the only new part is the cap. The points are fairly worn, but I ran sand paper through them and did my best to gap them to spec. (All before the drive)

Electronic ignition is on the list of upgrades, but I think front end bushings, ball joints, etc are next on the agenda. What look like the stock (or at least very old and cracking) bushings are just starting to allow some undesirable movement and noise in the right uca, so they're all getting replaced at the same time.
