Sounds like you need a good tuner.

Have you tuned the car? My 383 has a fairly good size cam, not huge but not small either and I make 13 pounds of vacume and the brakes work fine. I used a mail order tune to start with so i would not hurt the motor durring break in and it ran darn near stock from the work go in terms of how the car drives just with a whole lot more power. Without more information then what you listed it could be a many things. Just a stab in the dark if you do have a tune would be valve adjustment, it will affect vacume and make it run like crap but so would a vacumme leak. What are the specs of the motor, what tune are you running, do you have any data logs, does it run like a dog in open and closed loop, any codes?
