Everyone keep on the same page as to 4 degrees advanced from straight up and advancing a 4 degree ground advanced cam(when at dot to dot) an additional 4 degrees (or whatever)
remember that advancing the intake lobe 4 degrees may help DCR
However it also opens the exhaust 4 degrees earlier costing power- an effect which is greater on a low compression motor
