Here are some photos of the Corvair aircraft engine conversion for my Pietenpol Air Camper project. The Air Camper was designed by Bernard Pietenpol in 1929 and used a model A ford engine originally. Later Pietenpol was the first to use a Corvair engine in his design. My engine is based on the conversion design and parts developed by William Wynne at flycorvair.com and Sport Performance Aviation flywithspa.com. It is a bored out .030 2.7 Liter (164 C.I. originally) 100 HP engine. 3.0 liter versions are also popular using other piston/cylinder combinations and a 3.3 stoker option is available
