could you make a rough gestimate on timing advance curve for the following setup using the sert and 94 octane???
113 se
htcc pistons
cnc htcc heads
56mm hp inc throttlebody
d+d fatcat
.03 cometec head gasket
tman .650 cams 258 in 260 ex lobe centers are 99 and 110

i know this is a hard question to answer just looking for a place to start and some idea of how much advance these builds like ..
Thanks julius

H-D's timing curve is really conservative, ramping up to 24.5 deg at 7k. With your cams, you could add about 5 degrees to this timing so ramping from 8 deg at 1k, to 28 deg at 6k, then add more until you experiance detonation. It is rare to go much above 32 deg total on these motors.
