Default How will adding HP affect the stall?

For starters L76/Full bolt ons/3,9/Circle D 4000-4200 - (which is f'ing brilliant)

I was wondering if I were to add 100-130hp how it would affect the stall converter in terms of flash rpm, slip in daily driving etc. I thought it would go up and my builder says it will go down. I've tried to do a search but it's pretty hard to find any solid info. Anyone have any real world feedback on what to expect?

When you add more power, the converter usually loosens.

It depends on where you add the torque. If you increase low rpm and mid range torque it can go higher. If you are adding horsepower by going to a bigger cam, with no other changes, the torque at lower rpms will be down, and the stall will go down too. If a mid range cam with better heads, more compression, it can raise the stall. Superchargers raise the stall, more bottom end torque. Nitrous raises the stall. It is the torque that determines the stall. So it depends on how you are going to increase the power here.
