68 brake upgrade?

My browsing of the forum has led me to conclude two things about my 68 barracuda 440 project.

1) 5x4.5 pattern wheels are the way to go,

2) must upgrade at least the front brakes.

My 440 will have iron heads but aluminum intake. Lets say an extra 80-100lbs over the original 318. Can't I just leave the wife at home and stop better than stock? Lol
