Setting timing for /6 with new electronic distributor

Never worked on a slant 6....my daughter has a 63 Valiant with a 225 in it.

The engine is suppose to be a 71 year model, and still has a one barrel carb....it still has the point distributor also.

We are installing a new MP style electroinc ignition kit. New distributor..new ballast resistor and new ECU...got a MSD Blaster 2 coil. Also got a MP voltage regulator for the older style alternator.

So what should the timing be set at??????

Below is what we got..
