Putting the engine back together and wondering if the two items in the squares below are from the factory.
Item 1 is a plastic 90 degree fitting that goes to the power brake booster.
Item 2 is a some timing device I suspect this may of been installed later to comply with California smog check programs. Or is it original equipment?
Also looking for any factory correct 1966 HP 273 pictures that could aid making the top of the engine factory correct during reassembly.
