I could swear on my old manifold that was OPEN. I have that fitting and the other stuff that was in that hole was rotted out.
I thought the carb was a potential issue. The old one has a core charge but I have NOT sent yet.
I’m not going to lie.
Drilled it out 75%
Welded inside the stud
Welded on nut
Came out very well!
I installed the Dorman manifold. It was closed off on a top part where the old manifold was open.
