    That is a Wright cylinder.......for a tank engine. It is not an aircraft cylinder. Continental Motors built R975's under license during WWII for tanks. How would you like to cross Europe listening to that thing run......HUH? What ya say?

    Ahaa.
    What are your thoughts on using it on an experimental with a J-6? Or I guess a lamp base is a possibility.
    Thanks for your help.

    Now another question - How can I tell the difference between a Continental-Wright R-975 cylinder and a Continental 9A cylinder?

    I have no idea......I used all of my knowledge up in the first question. There are some video's on YouTube of a guy in England running one of those things in the back of a truck.

    Do the tank engines have dual ignition?

    Here is a picture of the back of a Continental R975 (Wright tank engine). It is upside down in the picture, showing the carb on top of the accessory section. Looks like dual mags, with starter on top (bottom) and the generator between the mags. This is the same as the R975 aircraft engines. The tank engines had a shroud and big fan installed on the front for cooling since you couldn't keep a tank going fast enough to cool the air-cooled engines (duh) which is why the tank engine cylinders have different cooling fin design than the aircraft engines. There are some parts that are interchangable with the aircraft engines, but not as many as you would think, which is unfortunate for those of us who operate Wright's.
