Because this article came from several authors, the statement of having about 50 degrees combined advance (initial, mechanical, and vacuum) at cruise rpm can be a bit misleading. That's the max some tuners would ever want to see, and some recommend using less- somewhere around 46 degrees combined advance would be perfectly acceptable in many cases. | Because this article came from several authors, the statement of having about 50 degrees combined advance (initial, mechanical, and vacuum) at cruise rpm can be a bit misleading.

| + | The same holds true for the exact amount of initial and mechanical timing. It is all but impossible to give ''exact'' numbers because of the variations in engine builds and conditions in which these engines run. | ||
But any way you slice it, it's still trial and retrial to get the curve dialed in. No matter what we do (short of digital control), the timing curve is always somewhat of a compromise, being as how all engines and vehicles (and all the other considerations) are different from case to case. So don't be surprised or alarmed if you end up with a curve that is different from what is presented in this article. | But any way you slice it, it's still trial and retrial to get the curve dialed in.
