The range of 737-800 high gross weight is about 5400 km with 162 passengers.
Boeing 757-200, again its high takeoff weight version, can cover 7200 km.
Boeing 707-320B with max fuel and 147 passengers can cover 9200 km.
DC-8-62 could cover 9600 km with max payload.
Surely, there could be more consistent and precise details. But as can be seen, Boeing 757 can fly missions that are simply out of range for 737.
However, 757, 707 and DC-8 are for some reason unable to compete with widebodies on long and thin routes...
