Kind of a what will it run

This is kind of a what will it run, but more like the difference.
I am going to be adding a trans go shift kit, 2500 rpm stall converter, 3.55 gears with a clutch style sure-grip. I ran it without any of this and 2.71 gears and ran 9.54 in the 1/8th mile. I am just curious what the time difference will be, any ideas? here is how it was set up when I ran last.
