    Ok, this is just vein curiosity; I’m not current planning to build a kit aircraft. I was wondering if the break-in process for an automobile engine on an aircraft (such as a Corvair) is the same for a normal aviation engine such as Lycoming (try to keep the throttle firewalled as much as possible for the first 50 hours).

    I didn't know that. I knew VW engines started out as airplane engines.

    So, would it be a true auto conversion if a Corvair engine went on an airplane?

    Not sure where you've heard that. Perhaps you are thinking of the Tucker...

    The Corvair engine was developed entirely in house by Chevrolet.

    Ed Cole was in charge of coming up with the design and he used his experience from being a member of the team at Cadillac that developed the M41 Walker Bulldog tank at Cadillac's Cleveland facility. The M41 was powered by a Continental AOS-895-3 engine. This was a six-cylinder, air-cooled, four-stroke supercharged boxer engine, similar to contemporary aircraft engines.

    Ed was also a pilot and flew his own Bonanza.

    Robert P. Benzinger and engine designer Adelbert “Al” Kolbe were given the task of developing the engine under direction of Ed Cole's Corvair team. The engine was named the "Turbo-Air 6," and was first built in the Chevrolet Engineering department in December 1957.

    Also, the Volkswagen engine was never based on an aircraft engine. It evolved from a Ferdinand Porsche design that started out as a two cylinder inline, similar to a motorcycle. When that design failed miserably, Porsche "borrowed" the flat four design of the Tatra engine and scaled it down to four cylinders.

    Any resemblance to aircraft designs in 1936 was purely coincidental.

    Yeah, I am an amateur automotive historian. I read a lot of books as a kid...

    Not any more, those grey cells have been reprogramed.
    Think about this, when did Franklin engine company go out of business?
    So, how would GM get one? they'd make it.

    I'm not saying they you are wrong here. However, what you said above doesn't support your conclusion. You are assuming your conclusion is true, and then using that conclusion to support your hypothesis.

    What has me skeptical is I know of a few copy engines, but things look similar but are different. For example old GM inline 6 cylinder, versus Toyota Land Cruiser inline 6, very different, but very similar

    When GM used it they put a bell housing on it.
