Drag strip question re 6 speed

If any of you run your LS-1 with 6 speed manual on the 1/4 mile I'd be interested to know what gear you are in at the end of the run. I've been going into fourth in my '99 but are not at 100 mph and suspect I can go through in 3 rd. What is the rev limiter set at in these cars? They do have limiters don't they? I calculate 6000 rpm is 105 mph in 3 rd gear. Seems doable without blowing anything up. Opinions?
Thanks,
Vinny

I have a MN6 tranny and I cross in the top of 3rd beginning of 4th, I have a 6600 redline though and usually show a 113-114 trap (on an accelerometer). Stock should be limited around 6k and shouldn't hurt anything, they like to be abused every so often.....
