From the start I built the Coronet convertable to drive. With 600+ ft.lb of torque, the 3.54 gear Dana seems to be geared too low. Even at part throttle a 1-2 gear change doesn't bring the rpms down at all. Instead, it feels like being rearended by a Grayhound bus! The 727 has a 9-1/2" 3,500 stall converter that is pretty calm at cruising speed. I think I could use an even lower gear, maybie as low as 3.0. Does anyone make a gear lower than 3.54 for the Dana 60?
