Another question about alternative engines

[Ernie Martin]

The engineering, certification and FAA approval would be a MAJOR endeavor, way out of proportion to the benefits, which I view as negligible to none. Then you'd be flying in a one-of-a-kind airplane that didn't benefit from the systems engineering that Cessna put into mating the TCM IO360 with the rest of the airplane. As a very young man I modified cars for racing. They never had the reliability of the factory (read: well engineered) models. The thirty subsequent years in space systems and jet engines reinforced the value of systems engineering. Sorry, but you would be far better off spending your money on a standard Skymaster that has been well maintained, and then keeping the aircraft in top shape.
