Any one interested in the oiling mods I did?

Remember the cross over mod was for engines using hydraulic lifters not solids.
Something I have found is that a step drill bit was used on the main to lifter galley by the factory on 340 blocks.
So be sure to run a drill bit thru there to open up the end of the passage.
As for whether you want to use the crossover as designed and created by Larry Atherton.

If you don't want to use it don't do it but there are those of us that know it works.

I'm running solid rollers, so that was certainly a factor. I'm intentionally not being confrontational about the topic, as I said, in the end we have all the info and anecdotal evidence in front of us, each person has to do with that what they want.

I drilled out every oil passage, blended corners, opened up the pump, etc. I did what I could that made sense inside my bubble of experience, in conjunction with the parts I was using.
