I need to work on my timing advance. I know what to do and why I need to do it, but doing a lot of research on what advance timing is and how far it should be set has me a little confused.<br /><br />I know if it starts predetonation and pings you have gone to far, so that is a dirty, kind of time consuming way to get it right. <br /><br />Here is an exerpt form a site explaining this.<br />"For example, part-throttle total timing would look something like this: 10 degrees initial + 10 degrees vacuum + 20 degrees mechanical = 40 degrees of total timing."<br /><br />I know boats dont have vaccum advance, so when someon eis telling you what your advance should be are they telling you the number on top of the initial timing, or are they taking that into account? <br /><br />I have a 73 307 V8, research for auto shows it can accept advance up to 40 degrees, and more under optimal conditions. That number is obviously taking into account the initial timing. What should I bee looking at for total advance at say 3000RPM from 0 degrees?
