Not saying that anyone is right or wrong with their ignition timing suggestions, but maybe some of you would like input from professionals who have done their dyno time. This first chart lists crank timing suggestions for less than 220 degrees camshaft duration @0.050" tappet lift.
Demon Fuel Systems
Click on the tab titled "Performance Cam Profile" for camshaft durations from 220 to 240 @0.050".....
Click on the tab titled "Radical Cam Profile" for durations up to and over 260 @0.050"......
