Trying to bleed a hydraulic clutch slave cylinder?

I’m at wits end with a muscle car aftermarket hydraulic clutch bleed. This has a reservoir up on the firewall with a rubber hose to the clutch MC, which has a stainless hose down to a slave cylinder. The bleeder screw is on the slave cylinder.
Bleeding the normal way like on brakes gets nearly no fluid out b/c the piston barely budges from a full stroke of the pedal. I’ve removed the pushrod from the slave cylinder and pulled the piston well out into the bore, uncovering the bleeder screw, and added a c clamp to prevent pedal strokes from pushing the piston out the end. Even with that rig, and my pressure bleeder pushing fluid down from the reservoir, I have virtually no pedal even though I’m getting no air. I should have a completely hydro locked immovable pedal now and I don’t. I’ve pissed 2 quarts of brake fluid through the system while in denial that what I’m doing will dislodge an air bubble and work eventually.
Just stepping away from it to cool down and figured I’d post on pelican OT in the event that anyone has any Jedi mind tricks for these that I’m not thinking about.
