Block off heater at intake, thread size?
Since I will have no heater in my Alfa-Dio build I need to block off all the unused ports in my Weber manifold.
I have one sample plug that came with it.
It appears to have some sort of sacrificial metal plug in it which prevents me from easily confirming the thread size.
Appears to be 3/8 Pipe, but since this is Italian I do not want to assume that.
So does anyone know the correct thread size for the small ports in the intake manifold?
Twin-Cam Hemi, Webers, Headers, Overdrive, Disc brakes, and no emissions equipment to spoil it all. These are gonna be FUN rides!
