There is a subculture of incredibly skilled hobby machinists turning out work that is awe inspiring for anyone who has ever stood before a milling machine or to those who simply appreciate great work. This V8 engine, built entirely from scratch, is one of those "best of breed" examples; fuel injected, double overhead cams, serpentine belt drive for the accessories and a smooth running sound that just amazes.
The project has a very detailed, two year long thread over at Home Model Engine Machinist, where builder keith5700 details everything he did, the troubles he ran into while learning his way through the tough spots and photos galore. You need to go through the pages to appreciate what he's done.
This isn't some CNC masterpiece, this is a manually machined and sometimes even hand machined project that looks like the full size prototypes it emulates. Those intake pipes on the manifold were roughed in on the mill then hand finished with a grinder.
Combining the skill in design, machining and finishing with the technical knowledge and skill of incorporating the fuel injection makes this a real masterpiece.
He's done some beautiful non-engine work before, too, the 1/8 scale helicopter rotor assembly is pretty spectacular in its own right. This is what a lifetime of learning, working and practice leads to, stunning work that can be appreciated by a wide range of hands on builders as work of the highest caliber. Very, very well done!
Thanks for the tip, William!
