Help me with my brake setup please..

[mnm99]

This is going to sound a little crazy,but... I'm building a twin turbo and planning for the future. I had a 11" booster then went to a dual dia 8" booster then to hydroboost for space. Had a problem with the hydroboost and now back to the 8" booster. I don't want to have the problems I had with the hydroboost again (got me stranded), Good thing because the headers I'm building won't work with the hydroboost anyway. I was thinking now about just a good manual disk master that will stop good. My current brakes are drum rear, 10lb residal valve in line. Disk single big piston 2 15/16" in front. I have a 1 1/8 master. As of now the brake rod is in the top (manual) hole. The car just wouldn't stop in the lower hole. I ended up shimming it there. I've been reading 1" - 7/8" bore masters, but I want it to stop good. What's your take on it?
