Hi all,
I have 2 O-290G's in my garage and always thought about using O-435 jugs on them. Before I go down this road, is there anything I should know about this contraption. I know the airboaters do this but is it safe for flight. Shouldn't a cylinder hold down pin be used? Also, what sought of injection is recommended? I have heard as much as 145hp and as much as 150 if an EI is used. Any truth to this? I appreciate thoughts from the engine heads!

Cheers
