Connecting rod bearings

[Fahlin Racing]

Hello all, hope things are well with all of you.

I am currently paging through bearing brands and I would like some help on deciding for my connecting rods to use in a build of mine if it no trouble.

What does the Dmax come with factory for con-rod material, grooved or ungrooved design?

Ungrooved, if I understand your question correctly.

Ok, thanks. Is anyone satisfied with Clevite, Kings or other? I have read some here and there on the forum about Clevite having a couple variations out there for performance use. Just curious about opening the topic of experience with any brand.

I used Clevite H in mine.

Clevite h in all the engines iv done with no issues

Bearing manufacturer is less of an issue as bearing design and intended use.

For example, when I was helping my dad build SBC's, we had trouble beating up lower mains with speedpro bearings that were grooved. We switched to a solid lower main of a different brand (I cant remember) and they held up because they had the bearing load capabilities that we needed. Speedpro has since changed lower main bearings that have a tapered groove that have more load surface. I'm sure the full grooved bearings would hold up just fine in a mild street engine.

That being said, not too many engines run a grooved rod bearing even when they have pressure lubed pins. We've never needed them. But then again I'm not an engineer :angel:

i just had my block totally redone with all new bearings, cant remember what type but here are the part numbers. mains-NS2218P std. rods-CB1855P they guaranteed the work knowing i have many modifications. hope this is helpful

Kool, thank you your experiences are great guys. This application will be full on drag racing and I don't think I will run a grooved setup though. I want to run aluminum bearings due to weight however we will see.

Thank you for posting the part numbers, I will look into them when I get the chance.
