>>it seems as if the 777 does have far more power than
the A340 (both
were fully loaded by the way).<<

Manufacturers don't usually put more engine on an aircraft than
is needed just for fun.  Each aircraft must be able to loose an
engine at V1 and continue a takeoff, at max gross weight, meeting
FAR part 25 climb criteria.  A two engine airplane looses 50%
power, and a 4 engine airplane looses 25% power.  Therefore, the
two engine airplane needs a higher thrust to weight ratio than a
4 engine airplane.
Now just because the airplane was full or people, DON'T assume it
was "fully loaded." Without knowing the cargo and fuel load, it's
pretty hard to make any assumptions along this line.
