318 Motor, please help

totally bonehead move on my part. now i have to ask this......can i just plug the hole on the back of the carb since i dont have power brakes, and just use a standard breather.......or do i need to order the PVC valve and connect it to the carb?
run a PVC. Use the hole in the back of the carb for the PVC. You need to ventilate the crank case. Usually, power brakes run off the intake manifold.
