Hi,
Most of us are finding that the timing is set a lot further forward. Like about 12 to 14 degrees. As to the dwell, I have never had an instrument to measure this. You should set the points at 0.015 and maintain that setting. This will change after the new points have been run in a bit. One way you may notice this is that the car may be a bit harder to start. By resetting the points to the original setting it will assist the starting. According to one of my books the dwell angle is 27-33 degrees.
Before setting your timing you can set the wheel to the neutral mark. Then if you want to increase or decrease the timing by a slight margin you can use the wheel. Otherwise you can loosen the distributor and set the timing by adjusting it.
Hope I am not steering you wrong here.
Charley
