The set that came in my rebuild kit do not have an oil hole (Clevite CB-481-P20 2130CP20). The old bearings in my engine had an oil hole pre drilled (Clevite 2130CP) Did I get the wrong part # or do I need to cut a oil hole in the bearings?

I'm running a 340 that I built in 07 and now have 10000+ miles on it. The acid test was the 120 mph blast on the salt flats for over 5 miles at a time, 3 times in 2010 on a 95 degree day! Then drove it to the top of Pikes Peak this summer when it was 95 degrees out. Drove it today. Last edited by Challenger 1; 10/22/11 09:07 PM.
