I hear ya on yanking the 460. I'm really glad I got rid of mine. 9 mpg on the freeway and 6.2 in town was getting old. I'm getting 18 mpg now with the 12v and I haven't done the low stall converter yet. The power this thing puts out is pretty impressive and working on it is a breeze.
On another note, I got these finished just in time for snow camping this weekend.
