71 Duster 360 turbo build

Max N/A power advance? Or max cruise, no load advance? In cruise, no load/light load you can be up around 50 degrees for fuel mileage. Power timing is dictated by how efficient the chamber is. Remind me what cylinder head you are using and what kind of chamber it has. You’re probably not too far off at 36.
I have the cnc speed masters with 65cc chambers. Probably not very efficient. I’m mostly interested in the max N/A number as a starting point when it comes to pulling timing for boost. I’m assuming I would need to make some N/A pulls and check straps to get an accurate number?
