Pedal effort should be same as a Fox Mustang with 5.0.  Is the clutch functional or is this all a brand new install?  Usually when I have someone with a stiff pedal it is because they melted the cable on the headers.  It does not appear that would be the case with your installation.

To test if the cable itselh has a problem, disconnect it from the release arm at the bellhousing.  See if the wire moves freely in the housing.  If it does, the problem is inside the bellhousing.

So I checked the cable without it attached to the fork.  Pedal is easily pushed in and cable moves freely in the sheeth.  When I hook up the cable to the fork, the pedal is pretty hard to push in.  Below are the things I have checked:

1. Routing of the cable
2. Correct adjustment. (I followed MS instructions that came with cable clutch)
3. I put tranny in gear and yoke would not move.  Wife pressed the clutch pedal in, yoke moves freely.
4. I took some pics of the throw out bearing contacting the pressure plate.  They are of the bearing released and engaged with the pressure plate.  '

Any suggestions are welcome.  Everything is new so I dont know if this is cause of the newest or am I missing something.  The pedal is so hard that the firewall is flexing and I can hear it creeking.  Thanks!

Looks like one of the spring clips (top picture) on the t/o bearing is not installed properly and is not in the slot where it belongs.  While that alone should not keep it from working right, it may be causing the t/o bearing to hang up on the bearing retainer tube.  Is this a used or new transmission?  Did you check the t/o bearing to be sure it slides freely on the bearing tube?  Sometimes the tube gets a little wear or grooved and the bearing will then hang up and not move freely.

What pressure plate are you using?

Did you use the pedal bearing conversion too?  I used his pedal bearings and clutch cable  setup.. and with a king Cobra  10.5 diaphram  clutch I can literally depress the pedal to the floor with three fingers

Sounds like you just need to have your wife push that pedal for you!  

Steve.......well that was just funny.  On I side note, she did get under the mustang and help me measure my driveshaft length.  It was funny to hear her say, "its dirty down here"....!!!!!
