How far should clutch fork move???

I have a old Lakewood bellhousing.There is no opening at the bottom like a stock one.So you can't see the clutch disk or anything.I guess you have to adjust the clutch by the feel of it.As far as moving on its own power.I just finised the driveshaft.Big U joint on the drive shaft and small yoke on the rear end.So I am going to have to pick up a big yoke at the Nats.Bummer I wanted to drive it around the block on open headers this weekend.Damn I'm so close.
Thanks,Jim
