I think I am going to take the plunge and change gears on my 1990 SuperCoupe. I have heard that the 3.73 is best for the automatic transmission. Will it be too low for highway driving and day to day use? I will not be drag racing the car and top speed is not a big consideration. I may run an occasional street autocross. I mainly am after quicker acceleration off the line and having engine run at a slightly higher RPM around town. The AOD hits second and third pretty quickly and lower gear would help with driveability. My question is, how low? Also, since I am not overly concerned with top speed, can I get by without a chip?
