Greetings all,I Really appreciate the time and input from everybody.Does any body remember the chart you may have seen in lots of car magazines that show you how to pick the CORRECT Carb for your car?Carb sizes across the top, and RPM from top to bottom?Is there such a Chart for Master Cylinder Bore sizes that work just as Quick and Easy?Clyde and/or Chuck recommend a 15/16 OR 1 ".How are you guys Figuring out this Bore size?What is the Math to make these calculations so I don't have to bother everybody again when Im building any other Project Cars I have? ?NONE of them will be stock and Ill need M/C bore sizes again?Im being told NEVER go bigger than I have to cause I will have a Harder pedal and less Desirable Feel.Flip a Coin,15/16 or 1"?How much REAL Difference in Pedal Feel and Stopping Power is there/can there be between a 15/16 and 1"?

Stop Tech used to have a guide in their White Papers section of their website, but the file is corrupted. I have a copy of an article from Car Craft Magazine, December, 2000, issue titled Braking Points: What It Takes to Stop Your Car. I tried to pull it up online, but had no success. If you'd like to PM your email address, I can send you a copy.

look for an oem 11" manual disc brake application, 73-74 Nova with manual front disc / rear drum used a 1" bore master.
most 69-74 GM cars (Nova,Camaro, Chevelle) with power brakes used 1 1/8" or larger.
Vega, Monza and S10s had smaller caliper pistons so they use .750" or .875" bores with manual brakes.
If you had S10 brakes which use 2.5" pistons I would use 7/8" or 15/16" bore for a manual master cyl.
