Gear ratio probably 3.70-4ish .
First gear ,I would say 1.76 just to labour the motor a little more off the line to help spool quicker.
Stall speed, 3800-4200,again to flash a little quicker to develop boost
Converter company - Neal Chance
What type of car is it anyway

Oh wow that's right along what I was hoping for. I have 3.90s now, but I was afraid that they would kill me on the highway or I wouldn't load the turbo enough with that steep of a gear. I'll Probobly leave it in there until I get everything else setup to see how I like it. That way I'm not building a rear end twice. I really appreciate the reply!!

And sorry forgot to say but it is a 97 trans am.
