Air Injection Exhaust Manifold Plug Size
« on: January 09, 2006, 09:51:00 PM »
Does anyone know the size and thread pitch to plug the exhaust manifold holes for the air injection hardware on a 74 350?

Thanks,
Larry

Larry, try a 1/4" npst. (nat'l pipe straight thread)  Naturally, you always want to use antiseize.
