Default What in the heck am I doing wrong!! Clutch issues

I've just recently did a engine/tranny swap and I'm currently sorting out the car. Ever since I replaced my old with a new clutch reservoir, slave cylinder and bracket I am not getting enough travel to fully engage my clutch. Got it well enough to put in gear (difficult) reverse is damn near impossible and if you gas it stopped while if first gear it lurches forward. Let me start with the components. Kirkham billet aluminum clutch master cylinder, clutch slave cylinder, bracket and Ram clutch assembly purchased from B2 Motorsports. I'm only getting around 7/8" of travel at the slave cylinder. My friends SPF with similar set up appears to be getting around 1-1/4" travel measuring the best I can from above and on a warm engine. I even put my original slave cylinder and bracket with the same results. There are two other SPF's in my area that are using the Kirkham master cylinder so rule that out. Okay, this is how I'm bleeding the cylinder from the very beginning. First...I have my buddy hold the clutch down and I open the bleeder valve on the slave cylinder. Close the valve and the pedal is returned to the up position. Repeat this set several times to get the bulk of the air out. Second...while my buddy is holding the pedal to the floor I open the valve and then push on the slave cylinder rod to get the air out and then close the valve before releasing push rod and repeat this a few times. Third...we hook up a radio controlled fueling device or pump after the device has been spun in some fluid to prime the pump. Using the pressure side hose it is slipped over the bleeder valve of the slave cylinder. The other hose of the pump goes to the master cylinder so all we are doing is recirculating the fluid. Fourth...I open the bleeder valve at the slave cylinder while my buddy cranks the pump. The valve leaks at the threads but still circulates the fluid and he indicates he can see air bubbles dissipate as he pumps fluid through the system. I have taken all the slack out of the push rod to see if I gain any throw but it does not make a difference. (Brent, in case you read this thread I know you don't approve but this is just testing here.) When I push the pedal all it has is resistance. My buddies with the additional travel has resistance and then eases up as you reach the floor. There has got to be air still in the system. What am I or we doing wrong or come to Memphis and fix her and I'll treat ya to some good ole southern barbeque?
