I get 8.18:1 DCR @ 10:1 static and 61.5 closing, and 168 lbs @ sea level.
Knock sensitivity includes water jacket temperature, spark curve, A:F mixture, etc.
If it knocks when you don't want it on opening throttle, reduce the initial lead and extend the advance curve, soften the advance rate, run a colder thermostat.
If it knocks at light throttle, your vacuum spark is too much, too soon, doesn't go off fast enough, or cruise mix is too rich.
When someone tells you "14.7:1 is correct" don't ask him any more questions.
