Tony,
I'm having the exact symptoms. Mcleod clutch came with the engine from Roush with an alumimum flywheel. Cold engine all's well but hot it's either hard (nearly imposssible) to get into reverse and like you have been all over the place with adjustments. One turn either way at the fork will cause slipping or hard to get in gear (and shift), really gets notchy and a grind once in a while. I adjusted the pedal to give me a little more throw and it did help some but there is still a tremendous difference between hot and cold. I'm concerned about going with more throw, I don't know what will happen mechanically with the diaphragm mechanism. Is there a concern of going too far? When it's cold it pops & snaps when I depress it all the way (engine off). It's also real jerky feeling as it nears the floor and watching the fork it gets jumpy at the same time. Did you notice any change with the dot 5 fluid?
I gotta agree that something is growing when it gets hot, Randy probably answered that for me, the flywheel. Hope someone has some suggestions for us. My car is new, 250 miles but I don't think this is something that"s gonna "break in". More likely - burn up.
