Intake Manifold - 400
In taking a closer look at the 400 engine in my 77 F100 project, I noticed someone has plugged an opening in the front right corner of the intake manifold (directly behind thermostat housing).
Does anyone know what this is, or what this opening is for, or why it would be plugged?
Thanks
Rick
