Just for reference, I called and talked to Dana Corp Tech Support today
who makes Clevite 77 Rod Bearings for AMC's and everyone else.
They said YES, they no longer put in the notches for the oil squirter holes.
The OEM's quit doing it, and they followed suit starting in 2003
because the OEM's found there was sufficent Piston Pin oiling from Crank windage,
and elimination of the squirter notch reduced manufacturing costs.
They also said the squirter used oil volume and hurt oil pressure,
and they eliminated it from Rod Bearings for all makes of engines.
This is what someone in this thread has already told us, thanks,
but since I was curious, I called the Bearing Manufacturer and asked.
The part number on the 360 +.020 Connecting Rod Bearing Box I have is
CB-960 P-20(8) with a Federal Mogul interchange part # of 8-3310CPA20
and the date code, 03J22CD1, appears to be 2003 ! so I'm not sure if mine have notches or not.
Motor is on the stand and not sure if I'm gonna pull a cap and look or not,
cause I'm just curious as to if the bearing I have are notched or not.
I've had difficulty having engine shops "check" things too.
They seem to just want to go to the next oversize to be sure,
and the profit margin is in doing the machine work and selling new pistons,
and they're not relying on someone elses work, is my guess.
