I agree with Mr. Brauning as well. It always amaizes me how many people think they are experts of something they've done once. There is a big difference between an engine builder and a parts assembler. If you are looking for performance and longevity, etc, you need your motor assembled by a engine builder, not slapped together by a parts installer. "what do you mean by properly align the thrust bearing?" is a scary thing to hear from someone who build their own bottom end... And I've heard that twice this week!
