One of Dad's postwar claims to fame was building some of the hottest flathead Ford V8's in middle Tennessee. The family race car was a 34 Ford 3 window coupe that ran on the local dirt tracks. The engines were bored 1/4" oversized, stroked 3/16", 11:1 compression, and ran on an alcohol/hydrogen peroxide mix. He also modified Lincoln Zephyr V-12 distributors to run on the flathead V-8 engines for a much hotter spark. When one finally came unglued at high speed, it looked like a hand grenade had gone off inside the crankcase!
