I had a nice flight to my father's farm yesterday and have two spreadsheet files that I'll post this weekend. But here are a few quick data points: WOT at 7500' turning 3600 rpm and burning 6.5 gph showed 151 mph, or 170 mph TAS (I guess this is "75% power cruise speed") WOT (wide open throttle) at 9,500' turning 3500 rpm and burning 6.2 gph showed 141 mph, or 164 mph TAS thottled back at 10,500' to "economy cruise" at 3000 rpm burning 3.8 gph showed 118 mph, or 140 mph TAS. That's 37 mpg, same as the 2700cc engine. That makes my Volkswagen look like a gas hog...
