Greg,
My 360 has extended wings, 10:1 pistons, and a 2 blade Hartzell. I have a
portable oxygen tank mounted behind the seats. I've climbed to about 14,000 on
maybe two occasions (mostly for cloud avoidance). The airplane was still
climbing strong at about 200fpm. All temps were normal. I'm not sure how much
higher it will go.

The oxygen tank is about 22 or 24 (cubic foot?) capacity. For flow you just turn
the knob on the tank until a little arrow in the tube matches your crusie
altitude that is displayed inline in the tube. Pretty simple but works fine.
The oxygen is nice even when flying at 11,000 or 12,000'.  You get where you're
going feeling better, no headache, etc.
