What is this Carter BBD port for?
This is the bottom side of my air cleaner:
I can't be the only one with a fitting like this on a 318 with a BBD. I didn't measure the OD, it's either 3/16 or 1/4. It just opens into the air filter space on the other side. It's larger than the tube (port 4) on the carb, maybe with some struggle it's possible to connect them with the same tubing.
I cold-started the engine today with that port (port 4) open, wow did the engine like it. I'd have to dial down the fast idle setting if I keep it that way.
The 1967 Dodge Monaco / Polara factor service manual (which I have) shows WW3 Series Stromberg (272, 273, 274 and 275) being used with the 318 (auto, standard, CAP, non-CAP). This car did not come with a Stromberg when it was new, with the poly 318. It came with a Carter (AKA Ball and Ball?) BBD.
The lubrication and maintenance section shows an exploded view of the air cleaner and filter, it does not show this port.
