find out where it tachs out at and shift like im guess in around 67 or 6800(give or take) i know from the distance from where my red starts on the tach)and push in the clutch right at 100 or 200 rpms before that. If you practice it enough and u have exhaust on ur car u can listen to the car as its reving and get used to the pitch and learn when its at that rpms.

I was looking for a more technical answer based on HP and torque curves.

what works better for me is to shift around 6200 rpms. No 2 cars are alike, so if you are looking for the optimal shift points in your car you need to make an appointmen at the local dino and do a few runs.

Yes, there is a rev limiter. The first time down the track I was not watching the tach because of the launch and it bogged down at about 7000

The SS m6 has 3.45 gears, sounds like alot of people are switching to 4.10 gears and are pretty pleased with the results.

Transmission:
TR6060
1st 3.01
2nd 2.07
3rd 1.43
4th 1.00
5th 0.84
6th 0.57

Final Drive Ratio 3.45

If you have a scanner, you need to scan to see when your manifold pressure starts to drop off. That will keep you in peek power. Sure you can shift a 6300 Rpms, but your power band dropped off about 500-600 Rpms before that.
Although stock with 4.10 gear I think you'll need the additional shift to 5th gear for quarter mile racing.
