Normally Aspirated 337 STC's
 

Would anyone know where one could find all current available STC's for a late model, normally aspirated (mouth breather) 337's?

In particular, I'm wondering if there is an STC for a bigger engine other then the 210 HP stock engines.

Thanks in advance for your assistance.

I don't really think there is such a list. It would be interesting to compile one, perhaps I will start a project to do that soon. You can get an STC list from the FAA, but it is very difficult to decipher which ones are available, and from where...

Meanwhile, the only engine replacement STC I am aware is available from Riley, now called Skyrocket LLC. (http://www.superskyrocket.com/). They will put 540's in for you.

I have the list of STC's starting with 336 thru 337H. It is 83 pages, 517kb in .PDF format if you want it I guess I can E-Mail it to you. I didn't see any engine replacements.
