    Hello, I've just put together my 68 350 and there are 2 vacuum lines coming out of the air cleaner. Does anyone know where these go? I don't have any spots in the tree or anywhere on the carburetor

    The big hose i'd put in the left valve cover hole on block and small one should have a place on that rochester.

    The air cleaner is very simple. The sensor has 2 vacuum nipples. One goes to the snorkel door, the other gets manifold vacuum. The large hose is the breather hose. It should go to the valve cover.
