You have a big block in your car, ie intend to go VERY fast, but you don't want to get into making the stopping power equall to the task???? No offense, you have done well with all the rest, but R U STUPID? If you wanna go fast you gotta have ALL the parts up to snuff and a single resivoir master cylinder IS NOT up to the task. If you ever come to this part of the country, I gaurentee they wont let you on our track because we try to avoid having guys launching their cars off the end of the track when they find they are unable to stop do to brake failure. Please, for your sake, and ESPECIALLY for all the other people out their on the public roads, FIX IT. Your car will thank you for it in the long run.
