Hey guys, in another topic I mentioned that I had found the FAA database for TCDS's on the web and it listed if the certificate was held in the public domain.
Well I was looking at the certificates and was pleasantly surprised to find out that the Stinson SM8A certificate is now a public document.
That aircraft was powered by a Lycoming R680 rated at 215 horsepower. Anybody have any idea as to how common are these engines out on the used market? And if they are rare, anybody have a recommendation for an acceptable modern substitute that may have the potental to be used in it's place?
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

I believe that the R680 was used in some variants of the stearman pt-13/pt-17/NS-2 trainers. If this is correct there should be plenty of cores and spares around take a look in the engine section of trade-a-plane. Also, if you are interested the air and space museum had the original blueprints for the sm8 at one time. Contact the Garber restoration facility in Silver Hill, MD for more information.
