Total Timing?

Gee, I have a distributor from Mancini (non-adjustable), With vacuum line disconnected I have 36.5/37* at 3000 RPM, 11* initial (vacuum line connected at curb idle (850 RPM)) and 52* @3000 RPM with vacuum line connected. Like I mentioned before I followed an article from Mopar Action/Muscle which ever (October 2003). My 360 LA with Magnums heads, Professional Products intake and Holley Street Avenger runns like a Champ.
