64 273, 904 kickdown

Mine was adjusted so that I had to just about stand on the pedal to get it to downshift. So I took it out for a ride yesterday, and tried it on a nice and clear road and stood on it. I really had to apply pressure with my foot to get it to downshift. So I got it home and popped the clip off the rod and screwed it out about four or five turns and took it back out for a test drive. It shifted at about 7/8 of the way to the floor. Should it be any higher than that?
