Need some clutch help please.

Need a little help on My '62 v6 305.
I replaced the slave cylinder and I just can't get it adjusted right.
Before the slave took a dump the clutch was tight and no slip.
Contact point was real low and when you released the pedal it would snap right back up. It would fry the tires and launch good.
I have bled the slave several times and today worked on adjusting it.
The pedal releases real slow. the contact point is real high.
I had it adjusted too far and the clutch was slipping( motor revving in 3rd and 4th)
I adjusted it back and got it to grab, but the contact point is really high.
I went for a ride and it was good and tight.
After 3-4 miles it the contact point became "mushy"
Grab, chatter, grab, try to stall.
I dumped the clutch and the truck just kinda took off.
I'm almost out of adjustment and the contact point is almost at the top of pedal travel.
What would cause this drastic change?
I'm adjusting the clutch at the rod on the slave cylinder.
All help appreciated.

sounds like you still have air in the system. they are a ***** to bleed. you need to bleed the crap out of it. do you have a pressure bleeder or a friend helping you bleed it? i had to back bleed several systems before to get the air out but you have to have a presure bleeder for that. keep on bleeding it.
the mushy feeling is air in the sytem and when you have air in the system the cluch engagement is high, but it would not cause the cluch to slip. you would have too much free play in the rod with air in the system. if you have no freeplay and the rod is tight would cause the cluch to slip.
hope this helps

Here's what I'm gonna try.
Place a large, clean container of brake fluid under my truck.
Run a piece of fuel line from bleeder into container.
Open bleeder, and pump for 5 minutes or so.
Close bleeder.
I've done this bleeding brakes by myself.
Any other suggestions.
Am I way out in left field on this?
