Can someone tell me what the stock shift point, mph and rpm, is for a car with 3.23 gears?

Also, if anyone has 3.73s, what are your shift pints by rpm and mph?

Thanks a lot!

 

Stock, don't remember. With 6200RPM rev limit
I used 5900, 6000, 6000 RPM and 41, 81, 125
MPH on my 3.23 car. After converter I had to
lower MPH a little for the "elasticity". For 3.73s
you would have to scale these MPHs by 0.86
(3.23/3.73). And depending on converter, engine
output and shift cycle times you may have to
fiddle a little more.
