 We have almost always used 30 degrees BTDC for the full advance and usually the vacuum retard capsule has been plugged off or removed(don't care what the idle advance is)./
The American V-8 engines with their advance in the 35 degree range is too high. You may wish to call Richard reyman at West Coast Cylinder Heads ; he has done planty of dyno work for this.
