I am building a Franklin 165 to put in my '47 Crusair which presently has a Franklin 150. The MA4-5 carb has a much larger air inlet than the MA3-SPA. Does anyone know how Bellanca handled the difference in air boxes & possible intake duct size for the 165 option? It would also be great to incorporate an air filter if I need to make changes. Any info will be appreciated.
