Clevite rod bearings - No hole ??

Gathering parts for 454 build. Ordered the same Clevite bearings that came out (CB743P20)..but new ones aren't notched. There must have been a reason for the notch, or is Clevite just getting cheap and skipping this step ?? Quick innerweb search have mixed reviews on whether the notch is required. Stock N353039 crank...street car. What's' the consensus here ??

Re: Clevite rod bearings - No hole ??

The reason for the notch was some of the ancient rods had a groove in the parting line that allowed some oil to shoot out to the camshaft. They have not been that way for many decades as far as I know. If your rods have the groove and you are running a flat tappet cam it would not hurt to put a small notch on the bearings. If your rods do not have the groove or you are running a roller cam just don't worry about it. To be honest with you if I was doing it I would not notch the bearings either way.

Thanks for the replies... Rods do not have the groove and I will probably opt for roller cam. I thought by notching them could also affect the integrity of the bearing.

If the rods do not have notches there is absolutely no reason to mess with the bearings.
