Power Brakes install (65 270 Dart)

Hello, as the title shows I'm planning on installing power brakes on my 65 Dart with the 273 v8. I have a new master cylinder with brake booster. Checked and it says it will fit it as long as the engine isn't a big block or hemi. And I wanted to know if anyone has tired or has installed power brakes on a Dart this old with or with out the 273 in it.
