is a two bolt main worth beefin up?

my old engine is on a stand in the backyard and i wanna rebuild it for my dads 71 blazer just in case the motor in it takes a crap. problem is its a two bolt main, is it safe to bore out, and throw in some performance parts (intake, cam, etc.)? or should i just rebuild it stock and have it as a back up motor sittin around?
