Normally I prefer an 8" converter with about 3% slip but in this particular street car this converter feels great on the street and strip, so I would not be very happy if I had it tightened up and it hurt performance because of the 3.23 gears. If this converter was tightened to around 5% slip the car may run better and MPH better, or maybe not....
