3.23 to 3.55

Guys, just read and learned a great deal from the excellent thread on convertors. My question is, how much more 'seat of the pants' speed will i feel changing from 3.23 to 3.55 gears? Cant go any deeper as the car is used for regular highway driving. Motor is a mild 360 running a comp cams XE262H cam (1200-5200rpm power band).
