I'll be ordering my connecting rods soon(hopefully in 2 weeks or so) and one option that I'm undecided on is having forced pin oiling. Basically, the center of the beam is rifle drilled so piston pin recieves pressurized oil in addition to the regular splashed lubrication. Is it something worthwhile to consider?

I don't know the exact cost of this option at the moment; just getting the ball rolling and my ducks in a row. I know having the end of the pin bore drilled for better lubrication is a popular option on the stock rods, and this appears to be a step up from that.

Discuss.

Just thinking out aloud but wouldn't that weaken the rod? Granted some had wrist pin knock, I have taken some apart where the wrist pin was worn out at the piston end, not where the bushing is. I think the drilled hole is best idea, and leaves the rod still strong.

The drilling is done in the strongest portion of the rod, right in the center.

Would the increased area due to the hole be stronger?
