It saddens me to hear you sold her. What could be better than owning and be able to fly such a glorious ole bird out there doing rolls and stuff but yeah $5 a gallon for go juice and I imagine she did a pretty good job of going through the fuel but ya gotta do what you gotta to do. Back in the 70's I had a 65 Chevelle that I built and the 12 1/2 compression ratio even pinged and rattled on 260 Sunoco but my buddy worked midnight turn at our little local airport and he use to give me avgas to mix with the 260 which was a good mixture just smelled a little funny and happy belated birthday.
