Comments by "John D" (@johnd8892) on "DODGE HEMI - Everything You Need To Know | Up To Speed" video.
Lots of cars with hemispherical combustion chambers even pre World War 1. Belgian Pipe 1905, Fiat 1907 Grand Prix racer. Peugeot Grand Prix Car of 1912 and the Alfa Romeo Grand Prix car of 1914 both were four valve engines also, Daimler, and Riley were also using hemispherical combustion chambers. https://en.wikipedia.org/wiki/Hemispherical_combustion_chamber Genius of Chrysler was to trademark and promote the simpler HEMI name and so make may people think they invented it and were the only ones using it. Worked well for them.
