That's pretty close to stock...
when I wind out 1st I'm always watching the tach... not the speedo... 2nd is just shy of 70... 3rd is around 100... other than that... no clue.

1st i think is like 25 or 30
2nd is like 60 or 70
3rd is (what everyone else says) about 100 (never got to redline in third on mine yet
)
4th is like really freakin fast

2nd is like 60 or 70

this is what i got from a caluculator using the ratios and tire size (which i estimated at 25" tall) and final drive ratio.. they seem pretty damn accurate so take it for what its worth
for an SS/sc @ 6500 rpm
1st-36.2 mph
2nd-69.6 mph
3rd-103.8mph
4th-137.7 mph
5th-175.1mph
the only variable that i may have messed up is the exact tire size.. but it seems pretty damn close
EDIT --im an idiot.. they have a tire size calculator at the bottom of the page.. changed the numbers
the site is http://www.izook.com/gearcalc.htm

Speedometer must be off....I know for a fact that mine only hits about 55 in 2nd gear...not close to 60. A friend also has an LS manual and his is the same.

Thanks everyone. I was having a debate with a co-worker on doing sprints from 80-100 and told him 3rd gear for me should be just fine. Needless to say he didn't agree.

From scanning it and going off the vehicle speed sensor, heres what I've found
1st = 37.2
2nd = 72.1
3rd = 111.3
4th = 149.8 (I think thats what it was, can't really remember)
5th = Don't know, computer started messing up when I broke the sound barrier
