Settings would be the same for points distributors or HEI distributors for initial timing. We set our small blocks at 10-12 degrees BTDC with the engine idling and the vacuum advance disconnected.

8 degrees BTDC is a good starting point. From there you can bump it up as long as there is no spark knocking and it does not hold back on the starter when trying to start.
