Regarding Ignition, I have used MSD for 25 years triggered by the stock points with the condenser out of the circuit. Only issue I've had it needing to dress the points if it has sat in the rain for a month or so. They corrode but a couple of swipes with a point file fixes that. Same points for years and years.
