The engine owner, Paul, works at an ultra precsion machne shop. When he gets bored he makes a new engine. All of them are "works of art".
He has done a 1/4 scale WWI Bently R-2 rotary, 1/4 Cadillac 1936 Flathead V-8, 1/4 scale Chevy 350 LT-1. He keeps thinking about a RR Merlin V-12.
Way to much spare time
