iirc vac advance is 10* and mech advance is10*

this will give you 10* at idle/low rpm 20* under cruse and the boost pressure retards it to 10* when your under boost. i found this to work very well for power and fuel econemy, way better than the locked dizzy a lot of people use.
I've been running this way since the install last November and haven't had an issue. If you mash the throttle under 3-5K it bogs a bit but I try not to drive like that anyway.

This is how I have it wired currently using the FC leading coil as wasted spark driven by a MSD 6A and a gutted ignitor and trailing going through the distributor.

In order for it to run right the wires from the magnetic pickup to the msd must be reversed. Red to green violet to red. Otherwise it will bog!
