Here's a handy tool.
MFactory® Competition Products - Gear Calculator
Just plug in your tyre size (eg, 275/45 R17), 3.27 final drive, redline for LS3 is 6600 and ratios for one of the LS boxes in the link below. Drag your mouse over the graph to find RPM for a given speed and gear.
Gear ratios - Magnum 6-Speed Transmission
When you click calculate it uses the "query string" in the URL to store your settings - which you can then bookmark for later. Here's one example showing 1500rpm in 6th gear for the "TUET11009" variant.

97km/h at the top of 1st gear and a top speed of 408km/h, nice!
