I am running Dart Iron eagle 72cc heads with 388, flat top pistons with 2 valve reliefs. 12 degrees initial and full advance by 2600rpm. Must run high test gas. It only pings if I try to run around town with the rpm below 1800 rpm with the 2500 rpm torque converter locked up. My compression is around 10 to 1. I also run a high volume water pump with a performance 180 degree thermostat, 4 core radiator, and clutch 7 blade fan. She holds 180 solid thru all kinds of temps. No pinging under normal driving and petal to the metal.
