Can someone tell me what the purpose of the hole in this part just off the exhaust manifold is? Did it connect to something? 1965 Acadian 194. do I need it again if Im putting in new exhaust? Sorry for picture quality and orientation.
That looks like a heat stove for the air filter on a 1970s Chevy 250. There would have been a hose going to the air cleaner to bring warm air to the carburetor in cold weather.
Its hard to find a picture, but a hose made of a paper type of material, or a metal pipe, Ive seen both types, would connect to the air filter snorkel on the bottom of the thermostatic valve that can be seen in the pick.
