Why advance timing?

Thanks for the reponses!

Just got back from another parts run and it's still running hot enough to steam a bit. Dieseled very briefly when I got home.

Maybe advance the timing even a little bit more? Hot start issue I was having with timing at TDC also got a lot better at 5* advance.

Saw a '68 cuda coupe while I was at NAPA... Made me smile. :)
