total advance ?
It should like around 34-36. I would play around with it and see what happens. Allso it is going to want some more inital timing. Stock is 5-6 BTDC but it way like a little more mabby as much as 10-15 BTDC. But if you go up that high you will need to limit the mecanicl advance in the distributer. Hook up a vac guage and bump up your initial timing till you get the highest vacum reading then limit your mecanicle advance to give you some thing agound 34-36 total.
