I have a federal Spec '76. Supposed to be 2 ATDC but with twin HS4 and header etc. I run at the 10 BTDC except when trying to pass emissions. Then I set it closer to 0.
You are supposed to set it as far as you can BTDC without pinging. I know when mine drifted a bit further than 10 BTDC I got some pinging under heavy loads.
