Idk bro, that's what I read

Highest I've heard was 2900 (OEM)

I'm going to try that break launch tomorrow and I'll le you know

"my theory" since I have a high stall converter already in, if I get shorter gears I will get up to my power faster pretty much my engine will be working harder at softer pedal,

What do you mean buy cruising in 5th and smashing the pedal, it reaches 3200 rpm , cruises 3200

i might have my oem stall off a few hundred, but the principal is still the same. but based off my rev testing and experience with american muscle, the stall on the z appears to be around 3200.

break launch won't show you the full stall because you need a trans brake to be able to reach that level of torque without break tires loose. but 5th gear pulls will be more close.

i might be misreading your theory. but if you have a performance torque converter, your low end revs should feel a bit sluggish off the line but quite launchy when you hit the stall. but it sounds like you are more aggressive driving so the 3.7 would push decent for you off the line, but thats if you have enough rubber to keep the tires from breaking loose.

notice the rpm, not matter what speed, in 5th, on full throttle it will maintain a close 3200+ always, it will never sit much lower than 3200. thats where the flash stall is. flash stall is where the converter is full locked 1:1 ratio from engine to transmission shaft. make sense now?

Alright bro, later I'm going to try brake launch and 5th gear,

I'll fith gear at around 60mph, you think that will show, if you have an exact mph that you use to measure it let me know and we can compare
