Reassembling a stock bottom end due to an oil pump gear failure, and I was told to get a set of Clevite H series bearings. There seem to be a few options, and I'm confused. If someone could get me a part number it would be greatly appreciated. I have searched around on several forums for a straightforward answer.

Thanks

It's the same part number but with an "H" in it.

Your machine shop should be able to have you the parts next day and at the best price.

My shop got me all my bearings for like $60. Rod, main, cam, not H series.

This is what you're looking for.

Thanks a lot. What about cam bearings? And why are there several different part numbers when you look up h series bearings on summit?

SH1349S is the part number for the Clevite cam bearings that I've always used.
You may find that the CB663H rod bearings have been superceded by CB663N. They have moved away from large chamfers on one side of the bearing, and gone to a narrow bearing with small chamfers on both sides.

Durabond CH-8 cam bearings.


Not sure why you would use H bearings for a stock build, the P bearings have better embedability...who told you to do that?

And I wouldn't choose an H bearing for use in a stock rod that is more prone to ovaling.

Already ordered sh290s cam bearings. Ill take your advice for the main and rods. Just figured I would need the h series bearings to spin higher rpms with the 847 cam (from what I have read and been told). But my expertise is in computers and not engines, so will take any good advice for sure.
