A long time ago someone very savvy with the Ls1's told me this method according to our slow *** Tach...pay attention..
1st-2nd-shift at 5,500rpm on STOCK tach
2-3-5,700rpm on stock tach
3-4-6,000rpm on stock tach....
This should get you just as close to rev limit without smacking it.
The BEST solution is to go get a small shiftlight(i prefer Harlan's) and set it to 5,800....shift when it comes on, and go!!! no more watching a tach, just concentrating on driving....
Hope this helps....remember these only apply in a all out race(drag strip) application when the tach is REALLY falling behind.
