QUESTIONS ABOUT BUILDING MOTORS

[LOCASH]

Having a professional do it is not an option so here we go...How does this work? Do I tear it apart and measure everything to order the rebuild kit or do I order the rebuild kit and have everything machined to fit it? I see bearings with measurements but how do I know which ones I need? I would like to make a 306 but I am a bit confused. I have done all of my own mods but I have never built an engine before. Hope this isn't to general. Thanks in advance.
