This Prototype engine was run for test purposes only. Only two were ever made before K&B was sold. Includes custom Bisson "Pitts Style" muffler.
This engine turns an 17 x 10 or 18 x 8 prop at 8,000 rpm with ease. However, It would be a shame to put this engine in an airplane, since no one knows what happened to the 2nd one, the only other one known to exist.
