how much initial timing mild 360 magnum

Are you saying that if I can start it with all the advance in the distributor by dropping 20 degrees with the msd 8983 at start I should go for it?? Won't it be susceptible to ping??? Is all advance in by 2500 a good starting point???

Does you MSD drop the timing 20* while it's idling?

why would it need to retard while idling>?
do you hit the button during idling periods or when you dump it at the track?
