While reviewing my KR plans and following the group, Geo engines were mentioned.
For what it's worth I have completed a 993cc Geo engine conversion with a Raven Design redrive. The engine has been tested, and I'm anticipating final inspection within the month. It is smooth, quiet, and producing considerably more HP than I calculated. And this is using a RevFlow carb, not the computer fuel injection. I'm very happy with the reduction drive and Jeron Smith, the designer. He has been great to work with, particularly because this was the first use of the engine on a Chinook.
