My take on the oiling system crossover tube for the small block

Well, that’s pretty interesting!!! I bought Atherton’s book when I did the build and was struck by how much similarity there was.

I remember reading that Bob Mullen and Co. we’re based in the LA area. Was Atherton in the same area?

Juanita told me she didn’t know much except the parts were sent to California and that it cost “a whole lot of money.”
...She helped her son “hide the amount” from his father. :)

I have long term plans to do a rebuild someday that’s more in line with the potential.

I'm not sure where atherton's shop was. But the guy I used to work for in Phoenix used to go over to it and taking parts and get parts from him. Back in the seventies he took his 340 over to atherton's and they put the crossover on that 340 block.
My understanding was that Atherton's shop was in his garage at his house.
By the way his crossover tube looked just like yours but I don't remember the writing on it. Or maybe I do.
Yes I do believe I saw that on his crossover tube. Old memories long ago.
