Quote: I think this needs more scrutiny before coming to a conclusion.
I am looking at my 440Source 4.250" crank (RB) and both the 5-6 and 7-8 rod journals have the lightening hole at an angle.
Very interesting, it seems it was intentional. You can put me in the group who didin't ASSUME it was defective without a clue what was going on.

For what it's worth, I had my 440 Source 400/500 kit shipped to a very picky machinist. He scoffed at the fact that I paid extra for a balance and I had to hear about the other 'balanced' kits he'd worked on that were terrible. I told him to check everything out and rebalance if necessary. When I picked it up he didn't have one complaint and I paid a very small fee for them to check the balance. He did substitute the Clevite rod bearings for ACL versions though.
