After six hours of break-in flight, I'm going to drain the mineral oil and put in Aero shell 15w-50 and torque the heads.

Nelson, I'm not exactly sure what you are asking.  Is CV "constant volocity" or "horse power"?  If you mean "constant speed", no it is not.  It is a ground adjustable prop and I pitch it to best match the engine to the airframe.  With the Bing carb., I also must keep an eye in EGTs which is effected by fuel flow which is effected by load, which is adjusted by prop pitch.  Anyway, not sure if this answers you question.
