Big Block oil pressure block fitting help

[Geoff Padgett]

Hello All

I need some help identifying a brass big block chevy oil pressure fitting. Years ago I got this on a LS-6 engine that I bought and don't know what is correct for, can someone please help me. I does have the weather head markings on it which leads me to believe it is for factory something. the large thread is 1" and the smaller thread is 1/2''
