What I know about converting to 650B is really about two things. Brake reach and pedal-to-ground clearance.
I recently converted an older Trek 330 to 650b. My only issue was the original brakes didn't reach far enough, so I had to modify the frame for modern recessed screw brakes and then use a pair of Tektro brakes that did reach. I can fit 38mm tires with no issue. I might be able to fit 42's too, but haven't tried.
I use 170mm cranks, and since the bottom bracket is high enough on this "sport touring" frame, I've had no issues with pedals hitting the ground.
So really, the frame wasn't exactly designed for 650b per se, but it does work with well as a 650b. I am loving the plush ride of larger tires and lower pressures.
