As gprocket wrote, your problem is likely the timing. The Pertronix doesn't necessarily fire the coil at the exact point that the old points did - some re-timing of the distributor is necessary.

I’m getting what looks like an OK spark and double checked the rotor position and static timing
How did you check the static timing? With my electronic distributors, I rotate them CCW until a timing light on the #1 wire fires. You need to turn them fairly fast to get the ignition to fire, so you end up going past the firing point - need to judge how far back to turn it CW to return to the point where it fired.
