The above weights are for engines that include the Diehl Accessory Case package, intake manifold, Slick ignition system and oil cooler. Front Drive (Direct Drive) Great Plains engines (when driven off the pulley end) are for use with wooden propellers only. Metal or composite propellers are not allowed. Octane requirements will vary with compression ratio as will horsepower output. Great Plains engines "are not" certified aircraft engines. They can only be used in homebuilt aircraft that are certified in the "experimental category".
