ok, i have gotten a good idea of what to set the timing at, but now its a matter of how to do it. i understand the curve is a direct input from the springs and that the max is from the bushing installed, by the way this is an MSD 85551 dist. what i dont know is how to set initial timing, or how to read it. i have a light, but am not sure how to interpert the data. is the timing the number that flashes at the 0* an the timing tab, or no. any help would be great. thank you.
