I have a 2000 touring. Engine is built to a 3-7/8?? (95 )big-bore kit Screamin Eagle, heads are decked and port and polished Screamin Eagle Pro CNC Ported, has a fueling 543 cam, as well as running larger valves in the heads, 1 7/8 super E S&S carb kit. Obviously I wouldn't be doing the 28B curve, what would be the recommended start for this build?

Hi Mike,

Thank you for your interest in Dynatek ignitions. I am not sure why you are discounting 28B as a starting point since that is exactly where we would suggest you start with this engine combination. If this runs well with no signs of detonation then you can try 30B and up. The general rule of thumb is to run the most aggressive curve you can without any detonation. If we can be of any future assistance please feel free to contact us anytime.
