I have a friend who had the C85 in his Commonwealth Skyranger overhauled using the O-200 STC (crank, rods, pistons, cam) and new Superior Millennium cylinders. That's the right way and at not too much more than these guys get to o/h a plain old engine. (Nice to have friends that like to help) I'll ask again what he feels about the performance increase but I know he's mentioned that it was significant. He's had this airplane for 40 years so I'm sure he's got a good feel for it.

Basically, it's like a C90 except the power comes at a slightly higher RPM. Would the extra RPM'S and Cubic inches allow for rated HP at higher altitudes?
