Do you mean 40 des total? It would be unusual to run a distributor with only 10 degrees (crank) centrifugal advance. Keith Craft recommended 40 deg total for my low compression motor but I'm running 15 initial and 37 total right now.

It may have been 40. It's been years since I adjusted it, as I've only driven it twice in the last two years, and would have to check my notes to be sure.
I know I did have to limit the centrifugal advance quite a bit so I could run more initial. Otherwise it would run hot, and the idle was a lot more lopey.
I run a Crane ignition control, which retards timing a bit during cranking, allowing for more initial advance.
My motor is 12.5:1 compression, and runs 110 octane race fuel.

What does the temp do when you are driving on the highway? Get it out when it is cool like this, get it on the highway, watch your temps before, during and after and report back. 210-215 is not going to damage much. Keep it below 225 and go for a ride in order to troubleshoot.
