Hydraulic Clutch Conversion, 915 transmission/Bad knee Options

[GeorgeRud]

Are there any members that have converted their larger engined flat 6 or V8 conversion cars to a hydraulic clutch? I tried a search, but couldn't find too much information. My problem is a very bad left knee that is not getting better (at least until I get a knee replacement done), and a very stiff clutch pedal on my 915 gearbox. Mine is one of the early ones without the spring assist, so it is not easy to hold the clutch in without seeing stars!

Does the hydraulic conversion make the clutch effort any easier? My factory six has much lighter clutch actuation , but I need to do something to lighten the force needed to actuate the clutch in my conversion car. If someone has the correct bores and stokes needed for the hydraulic conversion (or perhaps the actual parts to use), that would be very helpful.

I'm hoping that someone has gone down this road and can give me some feedback! Thanks in advance for any advice.

This thread talks about some of the hydraulic conversions people have done, including mine:

I have a 3.0 six with a 915 transmission in my car, but it's a '78 engine and trans, so I do have the over-center helper spring on the throwout mechanism at the transmission, and I added the helper spring down at the pedals as well to stay as close to stock as possible. The mechanical advantage can't be increased beyond stock without shortening the travel of the throwout lever, so I doubt you will get much relief from doing that before you run into inadequate clutch travel.
