Hey guys,
1970 Camaro; all the normal pro touring stuff... Twin turbo engine so no power booster on the brakes... Wilwood 14" W6A/W4A brakes. Depending on who I ask, I'm told I need a 1" or a 7/8" bore master cylinder. Which should I choose? I don't fully understand what the difference in normal usage is one way or the other?? This car will mainly be street driven with a little A/C and some drag racing...

Thanks!
