I think so yes. It reduces pressure inside your crank case which helps with seal and gasket performance. It has also been proven in high perforamnce applications to help some with power, but in those cases the vacuum is created by running hoses from the braethers to a check valve at the header collector.

For connection, you should have a place for a fitting on the intake manifold, either at the base of the carb at the back or on one of the runners. Put a fitting there and connect your power brake booster to it, then use the large fitting on the carb for your PCV

Hope that helps
