I saw on another post that someone stated that the power brake booster vacuum hose should be connected to the rear port of a Holley carb. I have a Holley 650 dp and have my PVC hose connected to this port at the rear of the carb. My power brake vacuum hose is connected directly to an intake manifold port. Which is correct?
Thanks in advance!

Should be to the intake.

Some cars have the hose connected to the carb, some to the intake. If it is connected to the intake, it is less hassle if and when you remove the carb. But the main thing is that it is connected to a strong vacuum source.

You have it correct already. Rear carb port is PCV, brake booster generally plumbed to intake.
