I know that this is a very popular conversion for the Aeronca Champ folks. I've heard that it really becomes an O-200 in almost all respects. But it remains, legally, an 85 hp engine. That's important to the Champ people, because once you cross the 90 hp line, a one time wing spar AD becomes recurring, annually, for planes with > 90 hp.
