1st my set up is 70 Chevelle, BBC, T56 12 bolt, C5 stuff all around (rear is LS1 F car, same calipers)...

So I did some reserch and now I have more questions, the stock disk brake MC bore is 1 1/8, and the manual brake MC bore is 1".... I have read you want to go smaller bore size. But how small??? Will the 1" master be right? I have also actually seen people reccomend a 78-79 Monte/malibu Manual master, It appers to have a 7/8 bore. I actually have a new one sitting on the shelf.

What do I use?

What does a smaller bore effectivly do, increase pressure and?

How does the pedal effort differ?

Will the 7/8 bore move enough fluid?

Will it bolt on?
I am to the point of pumbing the lines and need to know what master to run... I am eliminating the factory prop valve and going Wilwood adj....
