you must have posted the info on your size when I went home for x-mas, I just saw it now!
6/6 size 14
thats a big guy on skis!

since ride discontiued the mountain series and replaced it with the Yukon, its a good bet. they have a 169 board, with a 269 waist (which is about as big as you get)

There is also a (grumble, grumble) Burton Canyon 168 with a waist of 266, theyve also got a Bullet 167 with a waist of 267. The Bullet is significantly less expensive, but with your weight it might be a little to flexible for you.

those are your best bets. I dont know where you could find them in town, but those are about the biggest boards I can think of. (there are bigger, but then were in the 900 dollar range)
