Another guy that has been through this conversion told me that the angle of my release arm was all wrong and it should be pointing at 7 O' clock and push to 5 O' clock as you look down at it. Being a Boy Genius™, I thought, "Hogwash!" The fulcrum is the same, the pressure plate is the same, the release arm is the same. How can the angle make any difference?? So, another trip to the parts house where I purchase a "long" Chevy throwout bearing. I stick it in and lo and behold, the clutch pulls much easier. Boy Genius™ never took geometry, so I guess there are forces working here that I am unaware of. The other thing that, probably, helped is that the new bearing has a curved face that slides over the fingers of the Belleville spring easier than the flat face of the old bearing. The flat faced bearings are for Long or B&B clutches only.
I noticed that when I shut off the engine, I could hear air rushing into the booster. "This can't be good", sez I. I put a clamp on the hose where it connects to the booster and, again, the clutch pull gets easier.
Another thing that has been pointed out to me is the importance of eliminating as much friction as possible and setting up the booster so it pushes the release arm as straight as possible. These are valuable suggestions.
At this time I have an acceptable clutch pull. I'm still going to look for improvement until I achieve the fabled two finger pull each and every time.
