Way back in 1969 a friend had a copo Chevelle with a MA6 dual disk clutch. The clutch was soft enough that his wife had no problem driving the car. The clutch liked to stick to the floor whenever he tried to shift at over 6200 rpm. He eventually replaced it with a single disk racing clutch. The Chevelle was traded in when the kids started coming. If we had only known then how to make it work!
