Why are you wanting to convert from 27" (630) to 700c (622)? It's not a noticeable difference. The tire/rim availability of 700c is the only real reason (and there would be a fraction more clearance with 700c), but there are various options for the old 27" (630) standard. Jensonusa.com carry a fair selection of tires and even have a budget price wheelset for screw on freewheel that works for 126mm spacing.
I converted from 27" to 700c on a bike because someone sold me a cheap (but good) 700 wheelset, complete with tires. I must have re-spaced the rear triangle, but the brakes needed nothing more than realigning the pads. I could then run either 27" or 700c within a range of 126mm to 130mm with no problem as long as the brake pads were realigned each time.
