O200 STC

Joe, there are two STCs involving 0-200s. One is a total engine swap with an 0-200.
One is an overhaul using the guts of an 0-200: crank, rods, etc. (Some call this a “Stroker.”) Your engine would technically be a C-85 but will give you more horses- 93 or so. You can keep your same prop and you don’t have to install an extra fuel pump.
I have the Stroker on mine, paired with a 7148 prop.
It’s awesome. I cruise about 118 true around 2500 rpm.

I have a 415C with a C-75 that is getting long in the tooth but runs fine right now. I do an oil analysis each oil change and it makes a little metal, which I was told, by an AP friend, that is normal for that engine at that age, and since the compressions are in the range and it is sounding as good as it does to just go ahead and fly but keep an eye on it. I am doing research for that day we determine it's time to make a change. I have seen several 415Cs on Barnstormers with O200s installed, so there must be an STC out there. My question is who has it and how much does it cost? I'm not ready to make a move just yet but would like to have the information in my pocket. Thanks for your help.
