Sorry all. My post #12 got a bit confusing. The 4bbl manifold (771) is not installed. the 2bbl (559) is installed and has carb and all hoses run.
Any idea what year it is IE casting date etc?
My 4bbl (771) is a 66 casting. and my 2bbl (559) should be late 66 to early 67 as I have no reason to believe that it is not the OE manifold
