WHAT IS BLUEPRINTING?
Contrary to its name, blueprinting an engine has nothing to do with big rolls of paper that have strange, blue-colored drawings on them. Blueprinting an engine starts by designing it on paper first. Calculating things like compression ratio, piston pin (compression) height, displacement, and carburetor cfm requirements are all the beginnings of the true blueprinting process. From there it involves properly communicating your needs to the parts manufacturers and to your machinist and finally checking the parts, by hand, to ensure that they all meet your requirements.
That is, blueprinting involves first designing the engine to suit the purposes you intend to use it for, then building it meticulously with (likely custom made) precision engineered parts. You're gonna start with a block, which will need precision machining to spec, and then add those parts and components with care until you have a bulletproof engine. Sounds pretty straightforward..
