Hier das summary aus Lars "how to set timing" paper:

Lars’s Suggested Timing Specs for GM V8 Performance Applications:

• 36 degrees total timing (vacuum advance hose disconnected), all “in” by 2500-3000 rpm
  
• 16-18 degrees initial timing at idle (vacuum advance hose disconnected). Note that it may not be possible to achieve the 16 to 18-degree initial spec with the 36-degree total without modifying the distributor advance stop system. It is more important to achieve the 36 total than to hit an exact 16 to 18 initial. However, if your initial timing is very low (below 12 degrees) with the 36 total, it is important that you repair or modify your distributor in order to achieve correct engine performance
  
• 16 degree vacuum advance control unit with a pull-in spec that allows the full range of vacuum advance to be pulled in at the engine’s idle manifold vacuum level. Connect to manifold vacuum for most applications (this will allow the engine to idle with actual timing at idle of 34 degrees). The total maximum combined timing at light throttle cruise above 3000 rpm will be 52 degrees.
  

Ist bei mir (fast) so eingestellt und ich kann in Sachen Motorlauf echt net meckern...
