Wrong distributor for 69 318?

I've gone ahead and done the scientific thing - here's a graph of the advance with the vacuum unplugged, and put on ported.

The advance numbers (vertical line) are the timing minus my initial timing (11* right now, which still seems to be too much for it with the vacuum advance plugged in). This is with the
car sitting still in park. Vacuum goes right to 20" when I crack the throttle.
