I have mine set at 10 deg initial and another 22-24 deg centrifugal all in at around 2500 rpm crank degrees the vacuum pot is a 10 degree pot. It doesn't detonate with the 8 to one compression. The shape of the weights will limit the total advance. The springs will determine at what rpm you will obtain full advance. The number 8 stamped on your pot signifies it is an 8 degree pot you could open the slot a little for more vacuum advance if it isn't adjustable but 8 is ok if you can gain more centrifugal. You need to buy a rev kit to get lighter springs at summit or autozone etc. the rev kit weights may not give you enough advance . I used some weights from a Cadillac I don't remember what year. At the time I just looked at distributor weights in the junk yard cars and took some skinny ones as they allow more advance when they open out before they touch the cap limiting max advance. The timing light with the knob makes it easier to set it up just check the calibration against your timing tape.
