I have 1k + hours flying behind one of those engines and never trusted it. Only problem was vacuum pump failure in hard IFR, and a electrical failure from a broken alternator wire at 12K with center over the mountains."Back in the day" (O-320H2AD single drive magnetos) I flew several C-172's off county roads during a/c recovery. The local sheriff deputies would block the road for me.
When I had my accident (in NY) the state park officials demanded that the plane be removed before sunset, and the local cops (one of whom was my next door neighbor at the cabin) escorted us the three miles or so down to the road to where I'd arranged to leave it until it could be disassembled. Fortunately the road was wide enough.He did not disassemble it: he trailered it intact, and far exceeded the load width limitation.
