Distributor spring change

With what you have, and assuming the quench was built into it - I'd say similar to 67's idea. 15-18° initial, 18-20 centrifical for a total around 38°. Have the curve start coming in around 1800, and be "fully in" by 2400. Also remember - always set timing first, then adjust the carb. Once the curve's set you'll want to look at idle vacuum in gear and get the right power valve(s) and then jet it.
