The Lycoming performance charts show that the 360 can make 100 hp at a lower rpm and lower fuel flow than the 320.

A few weeks ago I ran the 360 in the Fuelventure competition at Meadowlake near Colorado Springs. I came in fourth overall after three Variez’s. it did 37.8 mpg around a triangular course of 378 miles at 168 mph (4.44 gph).

I flew at about 140-150 mph indicated and adjusted altitude with power. The power setting in level flight was around 16.5” at 1500 rpm, which is well off the chart.

It is a stock 360 A1A with mags and carb turning the old 2 blade Hartzel.

They are planning on taking it to Copper State fly in. I highly recommend it, they are a good bunch of guys engaged in friendly competition.
