Any one interested in the oiling mods I did?

All true, but if you have no reason to feed oil to the drivers side lifters...what does it do?

Once you stop all the leaks at the lifters and restrict the oil to the cam bearings you have effectively made the manifold bigger.

That’s why I’m stumped that we are discussing oiling hydraulic lifters and that’s what the crossover is for.

I don’t believe (I would hope) that no one would argue that controlling oil flow and restricting and/or stopping oil from where it doesn’t need to be increases power by reducing windage. A crank scraper does the same...it keeps oil off the crank and gets it back into the pan.

Im also going to pull my main caps and see what they look like. The rod bearings look like they came out of the box so I’m pretty sure they mains will be fine, but Duane says he was killing the 2 and 4 mains and not the rods. So I just want to get a look and make sure I’m not getting into an issue I haven’t seen before.
Yellow rose I said I hurt 2&4 mains because I put in a full grooved cam. That groove removed the restriction to the rocker gear.
There was full time oiling to the rockers. That lack of restriction bled off too much pressure from the mains and they got warm.
This happened in a tubed block with a high volume 70 psi pump.
It is a textbook example that pressure does not always go everywhere. The lack of a restrictor allowed the oil to bleed upwards
To the rockers through the grooved cam journals.
Now if you understand how this happens you should be able to understand that the crossover does the same thing. It redirects some of the oil volume.
