I took the next step and installed a Chrysler [type] magnetic pickup and reluctor. Installing the pickup onto the vac advance plate was super easy. Figuring out the rotor/reluctor phasing was the hard part.
I looked at the "all in one" products being sold and rejected the PerTronix/Stromberg types because they are proprietary.

In the photo I used the heat sink and coil off a late 90s chev V-6. The brain is a mid 70s HEI. Bulletproof and parts readily available at the local NAPA. Been running this setup for about 20 years and about 20,000 miles. Plugs look brand new; I think due to the high voltage/low amperage spark from the "e-coil" and variable dwell provided by the HEI brain.

Mechanical advance; 6 ° initial for a total of 22 ° at 2300RPMs
Vacuum advance; (manifold) 1 ° @ 6" 10 ° @ 10" [crankshaft]
