I just changed the clutch in my '93 F-150, it has the 300, 4.9, I-6 and a ford 5 speed tranny.  the clutch is hydraulic.  After installing it I bled it out a few times and now when I push the clutch peddle to the floor the clutch and the tranny are still somewhat enguaged.  I have the clutch peddle to the floor and if I take my foot off of the brake and I am in first gear the truck will start rolling.  If I want to put it into reverse, even though I have my clutch peddle all the way to the floor I still grind the gears.  Is there any way to adjust the clutch or do I have to bleed it out some more or something els?  

try pumping the clutch pedal a few times and see if it "pumps up" and helps. you may either need to bleed it better or possibly need a new slave cylinder. be sure and check for leaks.  

I think the clue here is clutch was changed. Something is different with throwout bearing height and it is not disengaging fully. Not familiar with that models clutch first hand but check to see if you can lengthen rod on slave cylinder a bit (most are adjustable) and that should fix your problem.  

Did you check the fluid level? My YJ done the same thing that you are describing,It simply needed more fluid.The fluid level was to low and it was sucking air.
