6th gear will gain you sometime but i dont see an 80 MPH cruiser out of that bus unless it had a significant HP bump and regear..

I'll second this ... our 3126 is a 210 HP variant. It likes to run 2350 RPM and up to 2500it is fine. It shifts gears up at 2600 RPM, so I have no problem running it at 2350 RPM all day long. We have an Allison 2000 with 5.5:1 rear gears turning 11R22.5 wheels. About the best I have seen is just under 75 MPH. It does like 68-73 MPH just fine.
