super bowl, give it time.

 

Here it is, direct from Wilwood (bottom of page):

I'm not sure exactly what ratio my set-up is on my car (it's been a few years since I originally set it up), but my MC pushrod is pretty much in line with the bore of the MC. With my MC mounted on an adapter plate (just below the upper two factory brake booster mounting holes), it puts the pushrod end about 1-2 inches above the factory stud on the brake pedal lever. I'm sorry that I can't give you an exact figure here, but my car is not readily available at this time, so I can't physically verify it for you.

 

When I first put manual in mine I used a ratio of about 5, pedal was a little hard to push so increased it to 6.5(I think that is what I ended up with--been a couple of years now). It has longer travel now but stops every bit as good as stock power. I must add that it might not be good for a light muscled person.
