Here is some solid advice...

Tstop on somewhere between .03 and .1. Try 0.05 to start.
Shift at .4
Tstop off at 2.75 seconds.
A data recorder is your friend. But you can do it without one. Goal is a consistent 60’ and is achieved with combination of Launch rpm, stop close time, shift timer, and stop rpm.
You didn’t mention the converter you plan to use. You want a fairly loose converter, stall 6600-6800 rpm. When the car is on the stop, you would normally like a converter that doesn’t creep more than 150 rpm when your stop is active. Less creep means your stop ratio will be more consistent. Once you get a baseline, you can start calculating your stop ratio. In general it will be some where around 2.5:1, it could be anywhere from 2:1 to 3:1. So to slow your car down 0.01, you would add 0.02 to your timer.
Good luck!
Edit, I don’t think it is necessary to make a wide open pass.
