Anyone home????? This topic should be bristling with opinions and questions, so I will try to revive it. I am designing and building a two seat biplane which will use the small block Chevy in a direct drive mode. I intend to use a crate engine, iron heads, hopefully an Aero Carb, small dia. headers, a towing cam and a basic electronic igntion, with duplicated coils and modules. The prop drive will be driven through a bellhousing (to be chosen still), a short flanged shaft which bolts to the flywheel (lightened?) and an endplate which will carry a hefty taper roller bearing to take thrust and gyroscopic loads, and a conventional hub. I will probably use an Ivoprop until I can determine the best pitch for the engine, but eventually I want to use a wooden prop in keeping with the rest of the airplane. Any thoughts on this? (Other than; it will be heavy...). I would like an exact weight for the small block, I cannot believe this, the most popular engine in this country and no one can tell me an exact figure! I am starting with 500 lbs. Radiator will be up front a la Curtis Jenny and the like .
