How far should clutch fork move???

Once you take the freeplay out of the clutch fork.How far should the clutch fork move?Mine moves 1 inch.Is this enough?I have a brand new ram clutch.I have a 383 and TTI's so I had to use a Hyd. clutch.
I have to put in some new U joints in.Then I guess I can get the car off the jack stands and see if it will move.If it moves it will be the first time since it has moved on its own power since 1995.
Thanks,Jim
