Re: vacuum line into manifold for booster?

Its very hard to compensate for harsh altitude changes with a carb. Other than physically getting out and rejetting the carb when you get to higher elevations theres not a lot you can do. Modern fuel injection will compensate but the carburetor cannot. Too much change in altitude will dictate a change in jetting. The issue gets worse the higher you go. The thinner the air gets the richer the engine will run and other than changing jetting theres nothing you can do about it with a carb.
As far as the brakes go you need to get a vacuum gauge on the engine and see what it has at idle. If your in the neighborhood of 15 inches of vacuum the brakes should work fine. Its hard to give you a definate answer without more info on it though.
