The 1930 Harley Davidson DAH hill climber and DAR export road racer was a hemispherical head as was the 1926 ,27,28,29,30 single cylinder AKA peashooter. Harley’s first overhead valve engine experiment in 1916 was a hemispheric as was Indian and a dozen or so other motorcycle manufactures . Its certainly nothing new and not an invention of Chrysler by any sense of the word .

I had nothing to do with it , have never seen one of those under water . I was in this cave when that story broke .

They are far less noisy then a logging truck smashing through your house .
