No you can not. When the PCV opens you will dilute the vacuum to your brake booster effectively reducing the amount of vacuum to it. Drill and tap a new hole preferably near the carb base, on top, and in a position to pick up vacuum from as many runners as possible.

Yeah, listen to Yatzee on this one.....it's your BRAKES. Another option if you have a big cam with low engine vacuum & don't mind the noise, you can put in a vacuum pump under the hood & just run your brake booster off of that.

What carb are you running? An edelbrock has a plug in the back for a booster port.

No big cam,just a 318 for now, I will have to take it to my machinist to get that port,holley 1850 600 carb.The said intake looks like wear the last owner had a fitting for something wear its going to be.

You can purchase a base plate with a port that bolts to the bottom of your carb.
