Vacuum Lines on modified engine
I was wondering with my motor swap, where exactly do my vacuum lines go now? I have a Quick Fuel 680cfm carb, and it has 1 vacuum port. I also have a large threaded hole in my Summit Airgap manifold, which I'm guessing is for my vacuum on my brakes? Can I hook a vacuum manifold up to the 1 port on my carb, and run from the manifold to the vacuum advance on my distributor and my HVAC vacuum lines? I no longer have EGR, air pump, or evap canister. Am I missing other vacuum line connections? Thanks in advance guys.

Vacuum advance on the carb port, PCV to the PCV port, HVAC and brakes to the intake port.

I'm using a Filter where PCV would go, is this harmful?

Re: Vacuum Lines on modified engine
One last question, it's off topic, but I didnt want to start a new thread. I have an 85 series Mallory distributor, I wired the coil no problem, but there is a harness coming out of the base of the distributor itself with a red, black, and brown wire. I could speculate and start hooking wires up to this, but really, I have no idea what they're for, and my directions dont even mention what they're there for. Is this a connection for Mallory's version of an ignition box? Or am I hooking this up to an existing set of wires on my car. I know my old distributor had connections on it because it was computer controlled, but this one is not. I'm slightly confused.
