Replacing the main bearings with clevite H series . These bearings have a full slot on the upper half . The slot is narrower than the oil hole restricting oil flow . Anyone dealt with these or have some input. Doesn't seem right ,am I wrong. A few pictures .

I put the H series in my gen 3 when I rebuilt it as well since the stock bearings were strangely way more expensive. The difference shouldn't really matter that much though. Oil is going to be under pressure, so it will find a way. I know some bearings will have a hole right where the feed is and then a slot on either side of it, but I'm not sure it makes a big difference practically speaking. My oil pressure actually went down with the Clevites, but that's more because the slot is longer on them than the stock ones, so it feeds the rods for more of the rotation on the crank.

Thanks for the reply. Might drill holes . Not sure. Would think the manufacturer would know what they’re doing.
