I put my 440 together recently, thought i did everything right and kept it clean...but, I took one of the rod caps off to double check it was on right and i noticed grooves running down the middle. So, I decided to tear the engine down again becuase I thought i wasn't clean enough and i was worried about it. Come to find out when i get the rods off, there are still shavings inside the oil passages of the crank...WTF. I had a crank grind and polish and stuff but i sat there and waited while it was hot tanked...I'm going to go talk to the machinist tomarrow and see what he says. Surprisingly i'm not that mad.
