HELP ..Need a Vacuum booster..

cap the vacuum port that is hooked to the booster , cap it right at the port and run the engine if it suddenly starts running properly he is right if it still rins like shyte he is wrong simple .As for the manual brakes get the bigger bore master cylinder from a manual brake bbody it will work great .Careful it will stand you on your head if you aren't careful while learning the lost art of threshold breaking but once you do you will never go back.
