Brake booster vacuum source
 

I just added a brake booster. Where should I hook up the vacuum hose? The 2 sources at the carb base are used for the distributer advance, and pcv valve. Do I need a T or is there another place to hookup. Thanks.

You can buy an carb spacer block with a vacuum port.

directly from the manifold. on the 350 there's a port you can use that is directly in back of the carb and in front of the distributor. i'm not familar with 6cyl so i dont know about that

The port on the back up the carb is where the pcv valve is plugged in. Do most just T off of that?

NO NOT OFF THE CARB OFF THE MANIFOLD!!

Anywhere you're getting full manifold vacuum would be fine. If there's not a port on the manifold directly (in which case I'd be slightly surprised if it's a V8) you should be fine T'ing in on the one on the back of the carb.

Mine comes off the manifold................

There is nothign wrong with going from the carb.
On the intake there should be a plug somewhere with a 1/2 inch (or so) pipe plug, get a fitting for that if you have no carb provisions.

Sorry cdowns. It would help if I would have read your post closer. Yes I do have the manifold plug you described. On my way to get a fitting.

Thanks for the help guys.

I say go to the junkyard and find the "t" behind the carb, on a car/truck with power brakes. Install that into your manifold.
