This working V8 displaces just 6.3 cubic inches, smaller than a coffee mug, but it runs, it’s supercharged, and it makes 16 horsepower from 103cc. Built by Ken Hurst and Dwight Giles of the Bay Area Engine Modelers, it drew a crowd at the Goodguys West Coast Nationals that full-size show cars usually have to compete for. See what a blown engine this small can actually do.
