nv4500 into 86 clutch issues

Okay guys swapping a nv4500 into a 86 k3500 that was original 6.2/465/205 truck. Using 93 external slave have it all hooked up and bled. 6.2 flywheel and 6.5 clutch...the problem is you push the pedal down and it's hard as a brick. No compressing it what so ever. Yes the disk is the right way :flipoff2: what am I missing?
