Carl,
I find the Drat Blocks seem to be machined much better with higher quality than the World stuff is. I have never seen anyone's line honing that is truly the same on each main journal, Dart is no exception. I always have to use several bearing sets to get clearances I want no matter if it is new from Dart or fresh for Reher Morrison or other shops.
Dart is using CNC Decking equipment. What is wrong with the decks? Most I am measuring are very close from one side's measurements to the opposite side's measurements, as close as .0002 . Not an error. That is three zeros.
I am willing to be educated though.
