Any one interested in the oiling mods I did?

Can you define “wet” lifters for me? I’m not exactly sure what that means.

Also, I always open the main feeds to .287 because I’ve seen many of those feeds that have steps in them. And I don’t want a change in cross section there.

I think .312 may be on the big side, but the limit to any flow will always be the smallest restriction in the circuit. For main/rod oiling that’s going to be the holes in the crank and at the very end, bearing clearance.

One last point is I’m pretty sure I have the Atherton book and several others that cover the velocity issue. One thing they never answered is how they determined how they tested for velocity in the gallery.

I must be the only guy who has never hurt a main bearing. Now I’m going to have to pull some main caps and have a look at my mains.

Some amount of oil flow to the lifters, maybe highly restricted, but some. I agree on the step drilled holes.
If my memory serves, there was a guy named Rapid Robert on the forum who has another book by Atherton showing that he pressurized an unassembled block with a garden hose flowing water through the galley to see how the distribution of each main was flowing. Apparently number 4 had very little water come out with the majority coming out the front.
When you kicked the rods out, was the journal blued or blackish in colour?
