Here is the setup:
-Edelbrock Performer RPM Airgap manifold
-Holley 700 CFM double pumper carb
How am I supposed to hook up my power brakes? The only port I see on the manifold is near the back of the carb, right underneath it. There is no way of getting a vacuum fitting in there. Is there anything I can do without running a spacer? ANY help would be greatly appreciated. I really want to get my car going. Thanks in advance.

 

Run the brake booster line into a pipe fitting in an intake runner of the manifold.

 

The only hole in any of the runners is the one I described. I talked to Edelbrock, and they said to get the low profile 90 degree fitting from them, but when I look at it, there is barely any clearance at all under the carb. Thanks.

 

carb spacer

 

I seem to remember reading an article in Super Chevy that showed a decrease in power when a carb spacer is used with the performer RPM airgap. Anyone know anything about this?? Thanks again.

 

Well, I'm officially an idiot. I didn't realize that the carb itself had a vacuum port on it. It's on the secondary side right under the float bowl. It was covered by a black rubber cap. Thanks for all the replies! I really didn't want to go buy a spacer.
