You would have an even better battery than the car maker expected you to put in that car. The car won't run better and the battery won't last longer.
The additional capacity means that if you charged it up you could sit there with the engine off and play the radio for a longer time before the battery was so dead that you couldn't start the car. It doesn't sound worth it for that.

Its not the 70 verses 90 that is the question. Its the CCA "Cold Cranking Amps" that is. Your battery capacity will be slightly higher and last longer under a load such as cranking the engine. A battery is only as good as its source i,e, the alternator and the load placed on the battery. Changing from a lower capacity battery to a higher one is not a problem, just means your charging time will be slower unless you change the alternator for a higher output unit?

From a mechanic
In this case nothing other then you might start the car a little faster.
It will start a little faster, but because of the voltage regulator it wont hurt it at all
