Similar vein, but not exactly the same - I really like the four stroke dirt bike engine building handbook. https://www.diymotofix.com/the-four-stroke-dirt-bike-engine-building-handbook.html Honestly, not very useful for the vast majority of folks but dirt bike engines are both pretty high performance and pretty simple so it's quite helpful if you're either (re)building one or if you're interested in how everything works and the practical realities of assembling everything. Also goes into useful tools and how they work and when I bought it I got both the e-book and the physical copy so that was a nice touch.
