Just bought everything for 3.73 gears

Hey guys I bought everything to swap my 3.23's to 3.73's mostly based on suggestions from a few fella's on here - so I want to hear from guys that run 3.73's or 3.91's even.. will I be able to drive the car on the highway, what are your cruising rpm's, what tire size are you running?
