hard or soft copper line for a valley oil gallery bypass line?

Why do you think Chrysler designed front oiling bosses right into the casting of the “X”
and “R” blocks if they thought it was not beneficial. The guy made you a simple drawing which is representative of the small block and asked you to explain why you are saying two columns of oil won’t flow. And you answer him with an insult. We had this discussion over 2-3 years ago and Rapid Robert was part of that discussion back then.
He had decided for his own reasons to perform that modification.
That Sanborn guy was a real racer who raced all three brands of small blocks and he said he could not get the Mopar to live until he performed those mods. That’s good enough proof for me and many others.
If it’s not for you, then yes we agree to disagree. But you came back on the forum with a new name and decided to have the whole conversation again. Bob Glidden used the crossover and oiling mods. That’s proof enough for me. The guy who developed the
Famed w2 head designed that oiling mod, that’s good enough for me.

Right. We will agree to disagree and I'll continue to point out the fallacy of oil velocity and such. Because that is wrong.

I don't care who publishes it or who used it. Claiming you use it for anything other than supplying oil to the drivers side lifter bank is nonsense.

I can't help that you don't like me being here under another name. That's on you.

And its clear that what's good enough for you isn't good enough for me.

BTW and IIRC the guy who wrote the "How To Build A Chrysler Stroker" (I'd type out his name but the book is back in the library and I don't want to walk back in there and get it and I don't want to butcher his name) isn't claiming its a velocity issue any more.

FWIW, Chrysler put that oil feed port up there for the dry sump guys to get the in at the front.

If the pump and the galleries are sized correctly, adding another oil feed does absolutely nothing. It's not one feed is feeding two mains and the other is feeding two mains. All that is coming off the same feed. Unless you pull the oil off before it gets to the main feed.
