Unless it's a stepped bore MC, 2 different size bores in one, the only difference in ports is the capacity of the reservoir. Disc brakes are self adjusting by allowing fluid to take up the space as the pad wears so the reservoir is larger.

If you want more holding power in the rear increase the size of the wheel cyls or calipers.

Thanks Brian, the one I have is a Strange. The 1.03 one, was in a k-frame kit for a 63 b-body (wasn't used) witch is ok since I'm using a 64 pedal. How is your car coming along? Who is gonna be out first, LOL?

Hey Mike, pretty much done here. Front alignment next week. engine has been on the dyno and I've driven it around the neighborhood, which I very much enjoyed, not sure about my neighbors !

Oh, you are my envy. I can't even push mine around the shop yet.

A smaller the master cyl piston bore will give you longer the brake pedal stroke with a corresponding increase in brake pressure.

When expermenting it's best to do it with a brake pressure gage, shoot for around 1100#.
