Hydraulic clutch cylinder sizes?

[powrby4d]

I’ve got a new to me SVC where the clutch has exactly the same problem - travel is extreme needing to go all the way to the floor where the clutch disengages only at the bottom of the stroke. However foot pressure requires tremendous force the entire length of the stroke, and depressing the clutch pedal results in a twanging spring noise. The clutch pedal has an odd bellcrank type arrangement in the engine compartment instead of being directly connected to the master cylinder. The car is basically not drivable with this setup. I was wondering if anyone has discovered this problem with an SVC kit and how to solve it, because my first thought is that this setup appears to be far more complex than it should be. Any advice would be appreciated before I dig into what is going on with the clutch and whether this strange bell crank clutch setup is a SVC thing and whether it should be replaced with a much simpler direct connect between the clutch pedal and the master cylinder.
