Thanks for your picture, Are you somewhat positive that's the original drain valve? I have 2 1970 L78 camaros both have the same forward facing valve tabs correct for a 1970. But one has the barrel flutted drain like yours and the other is without the barrel drain. Most likely there may have been different vendors for the valves. That one of the answers I'm trying to sort out. Also if they were painted. I feel they were installed when the radiator was installed in the car. So no paint should applied when properly restored. Also paint will prevent it from turning on the threads to open properly. GM always protected parts to prevent a service problems.

Here's a photo from a 22k original mile Norwood 04B 1970 Z28 formerly owned by Jack Seymour. Clearly has black paint on the petcock and the "ears" face the radiator. Original pic and zoomed-in pic.

I guess this throws a curve ball into this answer. So now we may be looking at 3 different drain valves for 1970. And a car that has one with black paint. Are there any pictures of Charley's former low milage 1970 Ls6 chevelle that show a drain valve?
