Any one interested in the oiling mods I did?

I lost 2&4 main bearings within 40 runs on my old motor due to excessive cam bearing leakage with 70psi pressure all the time.
I learned the hard way that cam bearings have to be restricted or you starve the mains. Number 4 main and number 2 feed the rockers. The block was tubed and plugged and still failed those two mains, but the rockers and cam bearing looked beautiful lol.

Ok, failing a main is a totally different issue than rod bearing failures while the mains are like new.

And I’m not suggesting to not restrict oil to the cam bearings. I think in my long post in the other thread I mentioned that, and if I didn’t I should have.

I usually use an .080 restriction in all of them and then I make sure that the cam journal on 2 and 4 are grooved, or I use a .060 in 1 and 3 and IIRC about .100 on 2 and 4 without a groove in the 2 and 4 cam journals.

I prefer the groove in the cam journal.
