Mystery solved:
1) points and condenser ignition was installed, along with new starter solenoid.
2) turned ignition key on and copious smoke and wire-melting resulted. Fortunately the old-school ignition was up to the current load and I could see which wires were affected- they melted.
3) traced fault to the tachometer pick-up lead which had a short to ground that was periodic (temperature dependant I am guessing) and not initially detected.
4) roasted wires replaced. Car starts and runs well. 4 ohms in ignition circuit. No shorts.
5) installed new petronix ignition. No smoke, Car starts and runs well. Tachometer works.
thanks for the input everyone.
