Timing mark question

Guys - I'm breaking in my fresh 350 and prefer to adjust the distributor position when I'm not trying to hold the RPMs up simultaneously.

If the mark is seen south of where I want it, by the timing light, in which direction will I tweak the distributor to bring it up a little?

Thanks!

I'm in the driver side fender and yes, using a vacuum advance off the Edelbrock.

are you asking which way to pull the dizzy to advance the timing ?

That's very helpful. Many thanks!
