284 484 cam and power brakes

Wouldn't going to a smaller bore provide better brake modulation and feel?

I thought power brake master cylinders generally had bores larger than 1" while manual master cylinders had bores less than 1". Smaller bore = more pedal travel for a given hydraulic pressure increase. My thinking is that it will be easier to modulate at maximum braking.

I'm in the process of upgrading master cylinder (single pot) on my '65 and I'm going to a late model 2-bolt from a dakota with 15/16" bore and a 2-4 bolt master adaptor.

My only challenge is to figure out how to retain the push rod in the back of the new set up.
