Ken Hurst and Dwight Giles of the Bay Area Engine Modelers brought a fully functional 6.3 cubic inch OHV V8 to the 2015 Good Guys West Coast Nationals — supercharged, running on nitro, and producing 16 horsepower from a displacement that fits in the palm of your hand. More than 1.1 million people have watched the footage since, and the sound it makes explains why. This is what genuine machining craftsmanship looks like when the goal is a muscle car engine at 1:7 scale.
