It depends on where it's going. The 767 generally has more power than a 737. If the 767 fills up with full fuel, then it'd be heavier and take up more runway. If it's a short distant flight, it will use less fuel therefore lighter and use less runway but still have as much power which is more than the 737.
The 737 is lighter than the 767 but the 767 has more power than the 737. Again I say, depends on how much fuel is put on the aircraft.
