Intake Manifold, what should this be connected to? (1 Viewer)

Is this intake elbow original to the build?

On my desmogged, Holly equipped 1977, this elbow, just below the carb, leads to a hose, which leads to... nothing (it's capped off)

I thought it might have once have gone to the charcoal canister through the VTV valve, but that appears to be a port in the carb base. The brake vacuum line comes off a port in the intake manifold and the PVC valve connects to the back of the carburetor. The cruiser runs fairly well (given all it's mods) I'm just wondering if I can remove the elbow, or cap it at the elbow?

Thank you all!
