Had some time this past weekend between finishing the paint job on the bathroon and moving bookcases to weld freeze plugs on the open ends on my two carb manifold project for my ohv six. I then fabbed up a bellcrank made from tubing, steel rod, bronze bushings and plate so both carbs will work together. Pictures to come soon:)

Now another task to complete on the manifold: anyone know the tap of the ohv manifold's pcv inlet... where the little elbow screws into the intake manifold. Want to be able to hook up a pcv at a future date.

Without checking one, I can suggest you try a 3/8" Pipe Thread Tap.
