I've got a 72 Blazer that I'm restoring and I'm getting ready to go through the brake system.

The truck came with a 307 but I'm going to put a big block in it.

Which booster should I use for room? Would the stock booster be ok or should I get a smaller dual diaphragm booster? If I should go away from stock which booster should I use and which master cylinder should I use? Will the stock master cylinder mount up the the dual diaphragm booster? Will the dual diaphragm booster mount up the the firewall and brake pedal?
