Birth of the Blue Missile
you sure about the 11:00 to 1......on pump gas???
just my "old school" experience.......
may I recommend under 10....closer to 9.5
our mopars (mostly big block though) like to have more advanced timing with lower compression vs the higher (above 10:00) and have to retard the timing....unless you like the spark knock on 92 octane...that retarded timing makes em' sound and run like a station wagon
maybe the newer stuff is different....
