On this one not really , usually we want all in at 2500 on a flathead engine, this thought can change with gear ratio, tire height etc. But usually 2500 is pretty good.
This engine has a blower on it and we need to push the curve to the right a bit , good response off idle and then add advance with boost....
You can play with the graph a bit and make up your own curve by drawing in a all in at 2500 rpm....
This one might like a few degrees less spark timing but its pretty hard to make a flathead spark knock assuming you are putting some fuel in the engine...i talked to the owner and he says he has never noticed spark knock with the 24 degree advance limit...
