I have a 1946 J3C-65 with a Continental A65-8 engine and a Sensenich W72CK40 prop. I fly it at sea level in South Texas, but I will be moving to the mountains of North Idaho. The airport is around 2200ft, but I am also surrounded by 74 mountain lakes near my property. I would like to modify it for floats to fly in the mountain lakes as well as skis for the winter time and still be able to put the tires back on for year-round fun.
I am looking for a recommendation and source for floats and skis as well as any guidance on installation instructions and FAA approval for these mods.
I would also like some recommendations for engine and propellor upgrades for adequate climb performance in a high-density altitude environment. The TCDS authorizes C-85-8 or -12 for land plane, skiplane and seaplane as well as the C-90-8F. I have also heard that you can obtain a 337 field approval without an STC for an O-200 if you limit it to 90hp by placarding the rpm gauge. I have a wooden wing spar, so I don’t think the STC version would be a good option. Considering engine and parts availability and performance, what would you recommend?

Rick
