Building or assembling engines can be an immensely satisfying task and performing this work yourself allows you to have complete control over the entire process. You will know exactly what components are inside the engine, where they were sourced from, and what power level and rpm they are capable of supporting. If you’re prepared to take the time to learn the fundamentals of engine building, practice the practical application of these techniques, and you’re patient, you can often produce an end result that’s better than many of the professionally assembled engines available.
