dual master cylinder

This means that the stroke of the pedal will need to be longer to displace an equal volume of brake fluid to match the original M/C. This could introduce issues with possibly running out of available pedal travel, and especially so if one circuit of the cylinder develops a leak.

I agree the pedal travel will be longer with a 1" master, but can be used safely with stock Ford pedals if care is taken to minimize floor covering below/around the pedal, and pedal arm bumper thickness to allow max travel. I'm using modified '34 and stock '40 pedals with 1" masters, and have full master cylinder travel.
