SC:
Not sure what you want the information for but I will give you some of my best guesses, first of all, the BE-90 is not even closely related to the Cheyenne III, the Cheyenne is twice the airplane of the small King Air, the Cheyenne can cruise in the mid thirties (9 PAX) at probably 270 KTS +, the small King Air is a 220 KT aircraft at best, mid twenties at best (250 for MU2), fuel consumption is 100 / hr on the Piper and the BE-90 probably burns 75?
I have no time on the Piper but some of the draw bracks would be the narrow cabin and spar cap in the isle, cockpit a little cramped too, the King Air is not great for long trips(SLOW), low wingloading and small cabin. Feel free to send me a message letting me know what type of mission you will use the aircraft for, I have many years operating this size a/c for charter / air ambulance and night frieght, is RVSM going to be required?
