Lets assume that I am using 3/4" master cylinders for both the front and rear of my FV. Does anyone have an approximate pedal motion ratio?
I am thinking somewhere between 4:1 and 6:1

We've always used 5/8" front and 3/4" rear masters. Wouldn't the ratio depend upon where the pushrod pivot is located in relation to the lower pivot on the pedal as well?

I think the last pedal we made was 2.5" from lower pivot to pushrod pivot and about 9" tall over-all.

The Tilton website has drawings of the pedals, cylinder mounts, etc. Lots of good info there.
My cars have brake elver ratios of 2.45 and 3.0, and other people's fees I've asked have as high as 3.5. I have the 3/4" rear & 5/8" front master cylinder combo.
As long as you can get in the foot box and m/c mounts you are working with. Are you starting with a clean slate?
My FV originally had this horrible brake pedal assembly that somebody grafted additional height on the pedal and it was still less than 3:1. I couldn't lock those tires up if I tried. I bought a Willwood 6:1 floor mount pedal and had to cut a bit over 1" off the pedal height, to get it to fit in the footbox. That ended up giving me about 5.29:1 and while a huge improvement....I still felt like I could tolerate more travel/leverage/modulation.
