What gear ratio will be going into the Charger? Its currently the 3:54 Dana in the car now correct?

At what RPM is the trans shifting at now?

What size convertor will be next? I remember you said it was a pretty big converter that made the car come off the corners well.

Are going with a taller gear and lower stall to get the drivetrain down in rpm so when your coming off a fast corner the trans downshifts into second and puts the engine right in that lower rpm of the fat part of the torque curve?

Also have you put the car on the chassis dyno to plot the torque and hp curves?

I know you do your homework and concentrate the efforts on maximum returns for time and money spent.
