Big Block oil pressure block fitting help
 

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''

high horse (4 bolt) oil pressure line fitting? Angled one went into that one

bbbently, are thinking of this one? This one threads directly into the block with no other adapter.
