Low oil pressure?

You need to stop the flow from the other direction if you bring the flow in from the front.

And BTW, that won't fix one single oiling issue. I've posted so much on here about that topic that I ain't doing it again. The oiling issue isn't about where the oil comes from, oil velocity, crossover tubes or any of that other bullshit.

A 1960's SBC will oil itself to 10,000 RPM's plus and not have bearing issues. If you want the truth, study a SBC and then figure out how to copy that.

Anything else s either bullshit or lies.
I know we have had that discussion before.
As I have posted before I am copying that mod from a very successful
Small block racer Charles Sanborn rest in peace. He looped a line around to the front.i have a good friend with an 8 second Daytona big block who has his main galley looped as well but from front to back.
Some things people are just gonna disagree on.
Sanborn brought the main oil line out of the block to a multi port filter block that divided it and sent it back to the rear inlet and the front inlet. If I recall you are referring to the timing issue.
I believe that issue has merit but I also believe that some blocks with a counter bore in the main saddles would adjust that. My 69 340 block never had those counter bores. My x block does.I suppose there will always be differing views on certain things.
