All Small Six PCV fitting

[Invectivus]

I’m converting my 67 Mustang to a large log head, and I bought the carb base from vintage inlines with a bell crank and PCV threaded port to facilitate. But I can’t find what fitting I need for that PCV port. Does anyone else know?

Are you talking about the thread size? And or the the hose barb size?
You probably need 1/4 male npt with a 1/2 barb. I just bought a pac of them for some air hose repair. I can get a pic of the fitting if you need
