Hi,
I was hoping someone could tell me what size mc bore a '63 classic/ ambassador would have if it came with power brakes. I have manual drums right now but I'm interested in swapping to a power brake system, retaining the drums all around. Also if you know what size booster normally came with these systems that would be great too. Thanks!

in it's 30 years, AMC/Rambler used only three different master cylinder bores: 1", 1-1/16" and 1-1/8". I got that info from factory Technical Service Manuals. http://wps.com/AMC/Brakes/

In general, a smaller master bore will mean less pedal pressure but more pedal travel for a given brake pressure. Power discs often got the larger bore, with lots of boost that would make brakes that are a soft touch with short travel (eg. "grandma brakes").
