MIne sounds like it's about ready to explode on the freeway, but that might be due to my lead foot and desire to cruise at about 85-90(approx since my speedo still has the 3.07 gear). With 3.73s, a loose converter and 275/60/15s I'm at almost 4500RPM at that speed, but she still runs fine. now 110MPH is a different story, that's where I really start to worry about the motor holding together.
