What stall torque converter do I run?

My setup currently consist of a rebuilt 318 with a hotter cam (no idea of the specs). 4 barrel Edelbrock carb, Rebuilt a904/a999 and a rear-end with 3.27 gears. I'm looking to get my converter rebuilt to a different stall speed, the current problem I'm having is that the motor bogs down when I shift it into gear from park, I'm pretty sure this converter came out of a slant 6 hence the stall speed being so low. Any ideas of a ballpark range of stall speed I should shoot for?
