Well I can say that Rang is good at what he does. Now as far as not plastiguageing the bearing clearances that is just foolish. Part of the builders job is to find any issues their might be. i.e. inproper rod cap on a rod mitch matched mains etc etc.....
When YOU put a motor together YOU should check everything because it is YOUR name on it. Unless you request it most of them are not going to check your rods crank etc etc. If you tell them to bore the block then thats what they do not check all your clearances etc etc.

If you want me to build the motor then bring it to me and we can work something out. you have my number. Ill stand behind it 100% and I will know what all your clearances are not assume the machine shop checked it.
