what kind of torque can you get with all the bolt ons and cam?

i see a lot of post about how much hp with these engines with bolt ons . That's not what I care about. I care more about the torque because that's what I will be doing just driving around town. Now what kind of torque will I get with headers, 4 barrel carb with aussiespeed manifold, Maybe a comp cam with the bigger duration, and full dual xpipe exhaust, and maybe milling the head .100 with oversized valves. and for sh*** and giggles what can I get with a m90 supercharger after all that.
