For those that want to build a -14 but can't absorb the cost of a new 70k engine I figured I'd start this thread and make a few videos. My -14 has been flying since Sep. 2021 with a 180HP parallel valve engine with favorable results.
Here's a video of a flight with that engine:

After 170 hrs of flight with that engine I decided that I wanted to upgrade the engine to the 200hp model. I purchased an IO360C1E6 engine on ebay for $7500 and drove out to California and picked it up. This was certainly a gamble, and as it turns out the crankcase was red tagged. However the crankshaft and cylinders were serviceable. So I lucked out. Starting with a core engine has it's benefits but if I had to do it again I might just buy all of the components individually. Divco will certainly have a crankcase and Aircraft Specialties will probably have a crankshaft. A few phone calls and you'll know.

Here's a link to the first video of the new engine build.

I won't be documenting every step on how to put the engine together, but there will be few more videos on the build and I'll do a flight a video as well.
The only change you really need to do using the C1E6 is the sump and intake tubes. Fortunately the guys that are doing the cowl flap mod are changing the sump and tubes and you can typically buy these parts for a reasonable price. The part numbers for these are the same as the IO360A1A as well.
Sump: 74384 (I believe any 360 200HP front induction sump will work)
Tubes: 78741, 78742, 78743, 78744
Note that the C1E6 is a great choice because it has the front left governor pad which is a must if you want a constant speed prop. I'm sure there are other variants of the IO360 that also have this and will probably work. One thing I wonder about is if you are building the tail dragger whether the accessory case driven prop governor will work because it appears that the only thing in the way is the shock absorber for the A model nose gear. If so than many of the 200HP 360's become a viable option for the dragger.
When I have some more time I'll add the costs to this post.
As far as performance data one can simply look at the two -14 prototypes. The -14A has the 390 and the -14 has the 360. The difference is negligible.
The cylinders are back from Gibson Aviation today and they look beautiful. Looking forward to getting home this afternoon to gap the rings and put the new pistons in.

With some luck and some good weather I should be breaking it in on Sunday.
Put the cylinders on this morning. Attached pics.
