Continental ECi engines has responded to the call to produce a stroked 360 engine with a counterweighted crankshaft. Their new 370 series engines are available with this option. This should prevent the vibration problems that were common in the higher-compression versions of their popular 370 series engines that resulted in a number of propeller problems. The engine, based on a stroked version of their parallel valve 360 cubic inch engine, has been popular with those builders who were looking for some extra power but didn’t want the extra weight of the 200 horsepower angle valve engine. No longer should those builders have to sacrifice a wide choice of propellers to get some extra power out of their engine.

He has so far completed four—two GlaStars, a Glasair Sportsman, and a Texas Sport Cub—and is helping a friend build an RV-8. When he isn’t building something, he shares his love of aviation with others by flying Young Eagles or volunteering as an EAA Technical Counselor. He is also an A&P mechanic, Designated Airworthiness Representative (DAR), and was a member of the EAA Homebuilt Aircraft Council for six years.
