MP DISTRIBUTOR TIMING CURVE 340

So do yourself a favor.
Hook the ported port on your carb, to the vacuum advance like it was designed. Set your timing between 12-14 initial 34-36 all in. And watch it purr like a kitten. And your cam is close to stock, so there should be no issues with idling.

Agree with this approach as a starting point. The motor running on your run stand is under NO LOAD. Once in the car fine tuning can be tweeked under real world conditions. Under hood temperature and drivetrain load changes will dictate how much ignition advance the motor will tolerate without detonation. Another big variable is fuel octane available at the pump in your area.
