Carb to manifold stud thread size.

[Richb77]

Im bloody useless with imperial threads and guess thats what i have here.

I have an Aluminium inlet manifold (no idea what from but its a Ford one) but no studs to hold the carb. Im not overly worried about the studs through the carb but what thread is in the inlet manifold?

Cheers

Not much to go on ! If it definitely isn't M8 metric then it could be 5/16" either UNF or UNC................but could be bigger @ 3/8"

I wanted to challenge you all 😁.

Ill measure them to find out.

if not metric then it will be 5/16 unc in manifold with the threads holding down carb being 5/16 unf.
