This engine that has been modified I/A/W Aviation Research Systems (now Check Six) came with an undamaged C35 Bonanza that I am parting out. The plane was undergoing an extensive restoration/upgrade and had one just like it in OH condition installed. It has been sold. I purchased the aircraft from an estate and apparently this was a spare core that the deceased owner had acquired.

There is no logbook nor record of it previously installed in this aircraft. It is offered as pictured except that the one stack is not included but both can be purchased separately.

Cylinders are chrome and I removed one to inspect internally. No internal corrosion noted and it does turn freely.

The manual copy and STC comes with it but it is assigned to this aircraft. It is my understanding that Check Six will issue a permission letter to another N # provided that the engine has their data plate installed. This one does.

The conversion is to install larger case studs and angle valve IO style cylinders making the engine capable of producing 260HP put apparently it is restricted with instrument markings to the original 225HP. It is compatible with the Bendix fuel injection STC.
